Details, quoting from Smithsonian National Air and Space Museum | Curtiss P-40E Warhawk (Kittyhawk IA):

Whether identified as the Warhawk, Tomahawk, or Kittyhawk, the Curtiss P-40 proved to be a effective, versatile fighter for the duration of the initial half of Planet War II. The shark-mouthed Tomahawks that Gen. Claire Chennault’s &quotFlying Tigers&quot flew in China against the Japanese remain amongst the most popular airplanes of the war. P-40E pilot Lt. Boyd D. Wagner became the 1st American ace of Planet War II when he shot down six Japanese aircraft in the Philippines in mid-December 1941.

Curtiss-Wright built this airplane as Model 87-A3 and delivered it to Canada as a Kittyhawk I in 1941. It served till 1946 in No. 111 Squadron, Royal Canadian Air Force. U.S. Air Force personnel at Andrews Air Force Base restored it in 1975 to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Chamber A
high precision engineering
Image by James Webb Space Telescope
NASA’s &quotChamber A&quot thermal vacuum testing chamber famous for becoming utilized in the course of Apollo missions has now been upgraded and remodeled to accommodate testing the James Webb Space Telescope.

When the next-generation space telescope was getting designed, engineers had to guarantee there was a spot large enough to test it, thinking about it really is as massive as a tennis court. That honor fell upon the famous &quotChamber A&quot in the thermal-vacuum test facility at NASA’s Johnson Space Center in Houston, Texas.

Chamber A is now the biggest high-vacuum, cryogenic-optical test chamber in the globe, and created popular for testing the space capsules for NASA’s Apollo mission, with and without the mission crew. It is 55 feet (16.8 meters) in diameter by 90 feet (27.four meters) tall. The door weighs 40 tons and is opened and closed hydraulically.

For three years, NASA Johnson engineers have been creating and remodeling the chamber interior for the temperature needed to test the Webb. Testing will confirm the telescope and science instrument systems will carry out correctly together in the cold temperatures of space. Additional test support gear involves mass spectrometers, infrared cameras and television cameras so engineers can hold an eye on the Webb while it’s being tested.

&quotSome of the items we’ve accomplished is upgraded our helium system, our liquid nitrogen method, and air flow management,&quot mentioned Virginia Rivas-Yancy, project manager, Air Flow Management Program at NASA Johnson. Temperatures in Chamber A can now drop farther than ever — down to -439.9 Fahrenheit (-262.1 Celsius or 11 degrees Kelvin) which is 11 degrees above absolute zero.

&quotThe air in the chamber weighs 25 tons, about 12 1/2 Volkswagen Beetles when all the air is removed the mass left inside will be the equivalent of half of a staple,&quot mentioned Ryan Grogan, Webb Telescope Chamber A project engineer at NASA Johnson.

A extremely large clean room is also being ready close to Chamber A exactly where the observatory will be prepped for testing. The test itself will take 90 days. The very first 30 days will consist of cooling the chamber down. The next couple of weeks will incorporate tests on the Webb’s operating systems, and the remainder of the time will be spent warming up the chamber to space temperature.

Test articles are usually inserted into the chamber by means of a precision mobile crane, but the Webb is so big, it will be folded up and wheeled in.

Particulars, quoting from Smithsonian National Air and Space Museum | Lockheed SR-71 Blackbird:

No reconnaissance aircraft in history has operated globally in a lot more hostile airspace or with such total impunity than the SR-71, the world’s quickest jet-propelled aircraft. The Blackbird’s overall performance and operational achievements placed it at the pinnacle of aviation technologies developments during the Cold War.

This Blackbird accrued about two,800 hours of flight time throughout 24 years of active service with the U.S. Air Force. On its final flight, March six, 1990, Lt. Col. Ed Yielding and Lt. Col. Joseph Vida set a speed record by flying from Los Angeles to Washington, D.C., in 1 hour, four minutes, and 20 seconds, averaging 3,418 kilometers (two,124 miles) per hour. At the flight’s conclusion, they landed at Washington-Dulles International Airport and turned the airplane more than to the Smithsonian.

Tv Shows We Utilized To Watch – British Tv show – BBC Till Death Us Do Component

Image by brizzle born and bred
Till Death Us Do Component was a British television sitcom that aired on BBC1 from 1965 to 1968, 1970, and from 1972 to 1975. Initial airing as a Comedy Playhouse pilot, the series aired for seven series until 1975. Six years later, ITV continued the sitcom, calling it Till Death…. From 1985 to 1992, the BBC created a sequel In Sickness and in Well being.

Designed by Johnny Speight, Till Death Us Do Part centred on the East End Garnett family, led by patriarch Alf Garnett (Warren Mitchell), a reactionary white working-class man who holds racist and anti-socialist views. His gentle and extended-suffering wife Else was played by Dandy Nichols, and his daughter Rita by Una Stubbs. Rita’s vibrant but layabout husband Mike Rawlins (Antony Booth) is a socialist.

The character Alf Garnett became a effectively recognized character in British culture, and Mitchell played him on stage and tv up until 1998, when Speight died.

In addition to the spin-off In Sickness and in Health, Till Death Us Do Portion was re-produced in a lot of nations, from Brazil to Germany (Ein Herz und eine Seele), and Hong Kong (All in a Household), with the most notable remake becoming the lengthy-operating 1970s American series, All in the Household.

Many episodes from the first 3 series are believed to no longer exist, obtaining been wiped in the mid 70s as was the policy at the time.

The series became an instant hit because, although a comedy, in the context of its time it did deal with elements of operating-class life comparatively realistically. It addressed racial and political troubles at a difficult time in British society.

The attitude of those who made the programme was that Alf’s views were so clearly unacceptable that they were risible, but some regarded as the series uncomfortable and disturbing.

Some had been oblivious to the fact that Johnny Speight was satirising racist attitudes. Ironically, several who held related opinions to the character enjoyed the show, maybe missing the point that Alf’s opinions had been offensive and that they have been getting ridiculed.

Mitchell imbued the character of Alf Garnett with an earthy charm that served to humanise Alf and make him likable. According to interviews he gave, the reality that some viewers overlooked Alf’s views and regarded him as a rough diamond disappointed Speight.

The show captured a essential feature of Britain in the 1960s – the widening generation gap. Alf (and to a lesser degree his wife) represented the old guard, the classic and conservative attitudes of the older generation.

Alf’s battles with his left-wing son-in-law have been not just ideological but generational and cultural. His son-in-law and daughter (a supporter of her husband rather than an active protagonist) represented the younger generation.

They saw the constructive aspects of the new era such as relaxed sexual mores, fashions, music, and so on. The very same things have been anathema to Alf – and indicative of every thing that was wrong with the younger generation and the liberal attitudes they embraced.

Alf was portrayed as the archetypal working-class Conservative. The subjects that excited him most had been football and politics, even though his actual information of either was limited.

He utilized language not considered acceptable for tv in the 1960s. He often referred to racial minorities as &quotcoons&quot and similar terms.

He referred to his Liverpudlian son-in-law as &quotShirley Temple&quot or a &quotrandy Scouse git&quot (Randy Scouse Git as a phrase caught the ear of Micky Dolenz of The Monkees who heard it although on tour in the UK – and who co-opted it as the title of the group’s subsequent single – although their record label re-named it &quotAlternate Title&quot in the UK marketplace to keep away from controversy) and to his wife as a &quotsilly moo&quot (a substitute for &quotcow&quot which was vetoed by the BBC’s head of comedy Frank Muir).

Nevertheless, Michael Palin writes in his diary 16 July 1976 that Warren Mitchell told him that ‘silly moo&quot wasn’t scripted, &quotIt came out throughout a rehearsal when he forgot the line &quotSilly old mare&quot.’ Controversially, the show was one particular of the earliest mainstream programmes to feature the swear word &quotbloody&quot.

The show was a single of numerous held up by Mary Whitehouse as an instance of the BBC’s moral laxity.

In a demonstration of Speight’s satirical skills – on finding out that Mary Whitehouse was a critic of the show – Speight designed an episode exactly where Alf Garnett was observed as a fan of Whitehouse. He was seen proudly reading her present book. &quotWhat are you reading?&quot his son-in-law asks.

When he relates that it is Mary Whitehouse – his son-in-law sniggers. Alf’s rejoinder is &quotShe’s concerned for the bleedin’ moral fibre of the nation!&quot

In the end &quotsilly moo&quot became a comic catch phrase. Another Garnett phrase was &quotit stands to reason&quot, typically just before making some patently unreasonable comment.

Alf was an admirer of Enoch Powell, a appropriate-wing Conservative politician known specifically for sturdy opposition to the immigration of non-white races into the United Kingdom.

Alf was also a supporter of West Ham United (a football club based in the East Finish) and recognized to make derogatory remarks about &quotthe Jews up at Spurs&quot (referring to Tottenham Hotspur, a North London club with a sizeable Jewish following). This was a playful touch by Speight, being aware of that in true life Mitchell was each Jewish and a Spurs supporter. In interviews, Speight explained he had originally primarily based Alf on his father, an East Finish docker who was staunchly reactionary and held &quotunenlightened&quot attitudes toward black individuals. Speight produced clear that he regretted his father held such attitudes – beliefs Speight regarded as reprehensible. Speight saw the show as a way of ridiculing such views and dealing with his complex feelings about his father.

The series switched to colour in 1972 and Rita had a infant son, Micheal.

Toward the end of the series Dandy Nichols fell ill and was unable to attend the live-audience recordings. The problem was solved by obtaining her pre-record her lines which were then edited into the show.

Ultimately even this was too considerably and so in a later episode Else was observed leaving for Australia, to Alf’s dismay. Patricia Hayes, who had been noticed from time to time previously as subsequent door neighbour Mrs. Reed, was offered a 1st name Min and became a starring character along with her husband Bert, previously played by Bill Maynard and now by Alfie Bass.

The show’s rating began to suffer and in 1975, the series was dropped. The final episode, saw Alf drop his job and get a telegram from Else asking for a divorce.

As with most BBC sitcoms Till Death Us Do Element was recorded before a live studio audience. The programs were recorded onto 2 inch Quadruplex videotape. From 1966 to 1968 the show was each taped and transmitted in black and white. When the show returned in 1970 it was recorded the exact same way only in colour.

The opening titles/end credits of the 1st colour episodes originally employed the b/w sequence from the 60’s tinted in red, as seen on UKTV Gold repeats in 2006.

Warren Mitchell (born 14 January 1926) is an English actor who rose to initial prominence in the function of bigoted cockney Alf Garnett in the BBC television series Till Death Us Do Component (1965-1975) scripted by Johnny Speight. He holds both British and Australian citizenship and has enjoyed considerable good results in stage performances in each nations.

Mitchell was born Warren Misel in Stoke Newington, London. He is of Russian Jewish descent[1], but describes himself in interviews as an atheist who often believes in God.[2] His father was a glass and china merchant. He was interested in acting from an early age, and attended the Gladys Gordon’s Academy of Dramatic Arts in Walthamstow from the age of seven. He did properly at college and read physical chemistry at University College, Oxford, for six months. There he met his modern Richard Burton, and with each other they joined the RAF in 1944. He completed his navigator training in Canada just as the war ended.

Dandy Nichols (21 Could 1907 – six February 1986) was an English actress most noted for her function as Else Garnett, the lengthy-suffering wife of the racially bigoted and misogynistic character Alf Garnett in the BBC sitcom Till Death Us Do Element.

Born Daisy Sander in Hammersmith, London, she began her working life as a secretary in a London factory. Twelve years later, right after drama, diction and fencing classes, she was spotted in a charity show by a producer, who offered her a job in his repertory theatre company in Cambridge. Throughout her early career on stage she acted beneath the name Barbara Nichols but later changed it to Dandy, her childhood nickname.

When the Second Planet War broke out, she returned to workplace operate but later undertook a six-week tour with ENSA. When the war was more than, she returned to the theatre and also began appearing in films: generally comedies and invariably as a maid or char.

Her successes in theatre contain the Royal Court Theatre and Broadway productions of Residence. Her large screen debut was in Hue and Cry, in 1947, followed with performances in Nicholas Nickleby, The Winslow Boy, The History of Mr Polly, Scott of the Antarctic, Mother Riley Meets the Vampire and Dickens’ The Pickwick Papers.

Una Stubbs (born 1 Could 1937) is an English actress and former dancer who has appeared extensively on British television and significantly less frequently in films or on the stage. She is particularly identified for her roles in the sitcom Till Death Us Do Component and the children’s series Worzel Gummidge.

Una Stubbs was born at Hinckley, Leicestershire. She very first appeared on tv as a single of The Dougie Squires Dancers on the British Tv music show Cool for Cats in 1956.

Her first significant screen part was in Cliff Richard’s 1963 film, Summer time Holiday. A handful of years later, she created her breakthrough in tv comedy, playing Rita Rawlins, the married daughter of Alf Garnett in Till Death Us Do Part. She also appeared in the quick-lived sitcom Till Death… (1981), once more playing Rita.

From 1970 to 1972, Stubbs appeared on most editions of It’s Cliff Richard! and It really is Cliff! on BBC1, singing, dancing and acting along with the host and the weekly guests. When she took maternity leave from the show, her Tv mother Dandy Nichols appeared on the show with Cliff to cover for her absence. She also appeared in the 1972 West End revue, Cowardy Custard, and two years later in the revue Cole, at the Mermaid Theatre.

Stubbs featured in the Fawlty Towers episode &quotThe Anniversary&quot. She played Rita a third time in a handful of episodes of the BBC sitcom In Sickness and in Overall health (1985-92). But right after 1986, she stopped appearing as Rita, due to technical arguments with the BBC. Even so, she played Rita a fourth time in the Granada series, A Word With Alf.

Stubbs played Aunt Sally in the ITV children’s series Worzel Gummidge opposite Jon Pertwee, and was for numerous years a team captain in the weekly game show Give Us a Clue. She had an ongoing role as Miss Bat in the Tv series The Worst Witch and has appeared in shows such as Midsomer Murders, Heartbeat, Casualty, Maintaining up Appearances and as Edith Pagett in ITV’s 2006 adaptation of Agatha Christie’s Miss Marple story Sleeping Murder. Stubbs has also appeared in The Catherine Tate Show playing a variety of characters.

On stage, Stubbs appeared in Noël Coward’s &quotStar Top quality&quot in 2001. She also appeared in La Cage Aux Folles at the Menier Chocolate Factory in 2008.

Antony &quotTony&quot George Booth (born 9 October 1931 in Liverpool, greater recognized as Tony Booth) is an English actor, very best identified for his part as Mike Rawlins in the BBC series Till Death Us Do Part. His daughter, Cherie, a prominent Queen’s Counsel, is married to former Prime Minister Tony Blair. He is a cousin to the Booth family members of 19th-century American actors.

Booth was born into a functioning class family members in Jubilee Road, Liverpool. His father was a merchant seaman during Planet War II, his mother was of Irish descent. He attended St Edmunds Infant’s College and spent a year in hospital as a child with diphtheria. He then passed the 11 plus examination and attended St. Mary’s College, Crosby exactly where he was awarded a bursary to cover the price of his books. Hopes that he could progress to university had been dashed when he had to leave college and get a job after his father was badly injured in an industrial accident.

Particulars, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Kawanishi N1K2-Ja Shiden (Violet Lightning) Kai (Modified) &quotGEORGE&quot:

GEORGE is the unlikely Allied nickname for the very best Japanese naval fighter developed in quantity throughout World War II. The official Japanese name and designation was Kawanishi N1K2 Shiden (Violet Lightning). This outstanding land-based fighter sprang straight from a floatplane fighter design, the N1K1 REX (see NASM collection).

Many countries utilized floatplanes for scouting and reconnaissance duties, and to hunt submarines and surface ships, but only Japan built and fielded fighters on floats. The Japanese Imperial Navy intended to use these specialized aircraft to achieve air superiority above a beachhead to assistance amphibious landing operations exactly where carrier or land-based fighters had been unavailable. The Kawanishi N1K1 (Allied codename REX) was the only airplane made especially for this purpose to fly in the course of Planet War II.

In September 1940, the Japanese Navy issued a specification for floatplane fighters capable of supporting offensive naval operations. A team of engineers like Toshihara Baba, Shizuo Kikuhara, Hiroyuki Inoue, and Elizaburo Adachi had readied the initial prototype by Might 1942, and it flew on Might 6. Tests showed that the speed of new airplane was only slightly less than the Mitsubishi A6M Zero (see NASM collection) and the amphibious fighter was virtually as maneuverable as its land-primarily based cousin. This was remarkable efficiency for an aircraft that could not retract or jettison its enormous landing gear.

Extended just before the very first Kyofu flew, Kawanishi engineers believed that the fundamental style would also make an excellent land-based fighter. The conversion appeared to entail basically replacing the major and wingtip floats with a traditional landing gear. The business decided to develop this variant as a private venture. As the project unfolded, the engineers decided to replace the 14-cylinder engine with a new 18-cylinder model anticipated to create about two,000 horsepower. The new engine essential a bigger propeller and this component, in turn, necessary abnormally lengthy landing gear struts to stop the blade ideas from contacting the ground. Kawanishi flew the initial N1K1-J land-primarily based fighter on December 27, 1942. The new engine failed to deliver the anticipated power and the landing gear functioned poorly. The airplane also fell quick of projected speed (649 kph – 403 mph) by 74 kph (46 mph) and could handle only 575 kph (357 mph). This was more rapidly than the Mitsubishi A6M Zero ZEKE, nonetheless, and the Japanese Navy badly required an powerful counter to new American naval fighter aircraft such as the Grumman F6F Hellcat and Vought F4U Corsair (see NASM collection). The Japanese Navy ordered Kawanishi to abandon two other fighter projects and start building Shidens.

By the end of 1943, Kawanishi delivered about 70 of the new fighters and the Navy employed these airplanes for pilot familiarization and coaching. Expecting Allied amphibious landings in the Philippines, the Navy sent the very first Shiden unit to Cebu in time to challenge Allied air energy supporting the invasion of that island in October 1944. Engine, landing gear, logistics, and upkeep issues plagued the Shiden units but Allied pilots realized they faced a excellent new Japanese fighter.

With N1K1-J production underway and Shidens flying combat missions, Kawanishi set about refining the design. They lowered the wings from mid-fuselage and the extra ground clearance permitted the engineers to install a shorter, much more conventional and less-troublesome landing gear, simplified the fuselage structure, and redesigned the empennage. Only the wings and armament remained from the initial design. The engine continued to give problems, but the Navy was impressed with these improvements and ordered the new version into production as the N1K2-J Shiden Kai (modified). In air-to-air combat, seasoned Japanese pilots flying Shiden Kais could much more than hold their personal against most American pilots flying F6F Hellcats. In February 1945, a brave pilot, Warrant Officer Muto, single-handedly engaged 12 Hellcats and shot down four of them before the remainder disengaged. Flying intercept missions against Boeing B-29 Superfortresses above the residence islands, the Shiden Kai was less effective since of inadequate climb speed and energy loss at high altitudes.

Kawanishi developed a number of other variants and planned a lot more when the war ended. About 1,500 of the various models had been created. In battle over Formosa (Taiwan), the Philippines, Okinawa, and the house islands, Shiden pilots acquitted themselves nicely but this superb airplane was yet another very good design and style that appeared too late and in as well few numbers to reverse Japan’s fortunes in the air war.

NASM’s Shiden Kai is one of 3 remaining today. The other two are displayed at the U. S. Air Force Museum in Dayton, Ohio, and the New England Air Museum in Windsor Locks, Connecticut. American intelligence units collected 4 GEORGE fighters from numerous Japanese airfields and delivered them to Yokosuka Naval Shipyard for shipment to the United States. The NASM GEORGE came from Omura or Oppama Naval Air Station, Japan, and the fighter arrived stateside aboard the escort carrier &quotUSS Barnes.&quot It was probably evaluated at the Naval Aircraft Factory at Philadelphia, and then moved to Willow Grove Naval Air Station. The GEORGE remained outdoors on show and steadily deteriorated along with a group of German and Japanese airplanes till 1983 when the Smithsonian Institution acquired it. The airplane was stored at the Paul Garber Facility until NASM loaned it to the Champlin Fighter Museum in Mesa, Arizona, for restoration in December 1991 and the project was completed in November 1994. The restored Shiden Kai wears the colors and markings of the 343rd Kokutai, a unit stationed at Omura Naval Air Station in 1945.

Details, quoting from Smithsonian National Air and Space Museum | Boeing B-29 Superfortress "Enola Gay":

Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of World War II and the first bomber to house its crew in pressurized compartments. Although designed to fight in the European theater, the B-29 found its niche on the other side of the globe. In the Pacific, B-29s delivered a variety of aerial weapons: conventional bombs, incendiary bombs, mines, and two nuclear weapons.

On August 6, 1945, this Martin-built B-29-45-MO dropped the first atomic weapon used in combat on Hiroshima, Japan. Three days later, Bockscar (on display at the U.S. Air Force Museum near Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Great Artiste, flew as an observation aircraft on both missions.

Long Description:
Boeing’s B-29 Superfortress was the most sophisticated, propeller-driven, bomber to fly during World War II, and the first bomber to house its crew in pressurized compartments. Boeing installed very advanced armament, propulsion, and avionics systems into the Superfortress. During the war in the Pacific Theater, the B-29 delivered the first nuclear weapons used in combat. On August 6, 1945, Colonel Paul W. Tibbets, Jr., in command of the Superfortress Enola Gay, dropped a highly enriched uranium, explosion-type, "gun-fired," atomic bomb on Hiroshima, Japan. Three days later, Major Charles W. Sweeney piloted the B-29 Bockscar and dropped a highly enriched plutonium, implosion-type atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. On August 14, 1945, the Japanese accepted Allied terms for unconditional surrender.

In the late 1930s, U. S. Army Air Corps leaders recognized the need for very long-range bombers that exceeded the performance of the B-17 Flying Fortress. Several years of preliminary studies paralleled a continuous fight against those who saw limited utility in developing such an expensive and unproven aircraft but the Air Corps issued a requirement for the new bomber in February 1940. It described an airplane that could carry a maximum bomb load of 909 kg (2,000 lb) at a speed of 644 kph (400 mph) a distance of at least 8,050 km (5,000 miles). Boeing, Consolidated, Douglas, and Lockheed responded with design proposals. The Army was impressed with the Boeing design and issued a contract for two flyable prototypes in September 1940. In April 1941, the Army issued another contract for 250 aircraft plus spare parts equivalent to another 25 bombers, eight months before Pearl Harbor and nearly a year-and-a-half before the first Superfortress would fly.

Among the design’s innovations was a long, narrow, high-aspect ratio wing equipped with large Fowler-type flaps. This wing design allowed the B-29 to fly very fast at high altitudes but maintained comfortable handling characteristics during takeoff and landing. More revolutionary was the size and sophistication of the pressurized sections of the fuselage: the flight deck forward of the wing, the gunner’s compartment aft of the wing, and the tail gunner’s station. For the crew, flying at extreme altitudes became much more comfortable as pressure and temperature could be regulated. To protect the Superfortress, Boeing designed a remote-controlled, defensive weapons system. Engineers placed five gun turrets on the fuselage: a turret above and behind the cockpit that housed two .50 caliber machine guns (four guns in later versions), and another turret aft near the vertical tail equipped with two machine guns; plus two more turrets beneath the fuselage, each equipped with two .50 caliber guns. One of these turrets fired from behind the nose gear and the other hung further back near the tail. Another two .50 caliber machine guns and a 20-mm cannon (in early versions of the B-29) were fitted in the tail beneath the rudder. Gunners operated these turrets by remote control–a true innovation. They aimed the guns using computerized sights, and each gunner could take control of two or more turrets to concentrate firepower on a single target.

Boeing also equipped the B-29 with advanced radar equipment and avionics. Depending on the type of mission, a B-29 carried the AN/APQ-13 or AN/APQ-7 Eagle radar system to aid bombing and navigation. These systems were accurate enough to permit bombing through cloud layers that completely obscured the target. The B-29B was equipped with the AN/APG-15B airborne radar gun sighting system mounted in the tail, insuring accurate defense against enemy fighters attacking at night. B-29s also routinely carried as many as twenty different types of radios and navigation devices.

The first XB-29 took off at Boeing Field in Seattle on September 21, 1942. By the end of the year the second aircraft was ready for flight. Fourteen service-test YB-29s followed as production began to accelerate. Building this advanced bomber required massive logistics. Boeing built new B-29 plants at Renton, Washington, and Wichita, Kansas, while Bell built a new plant at Marietta, Georgia, and Martin built one in Omaha, Nebraska. Both Curtiss-Wright and the Dodge automobile company vastly expanded their manufacturing capacity to build the bomber’s powerful and complex Curtiss-Wright R-3350 turbo supercharged engines. The program required thousands of sub-contractors but with extraordinary effort, it all came together, despite major teething problems. By April 1944, the first operational B-29s of the newly formed 20th Air Force began to touch down on dusty airfields in India. By May, 130 B-29s were operational. In June, 1944, less than two years after the initial flight of the XB-29, the U. S. Army Air Forces (AAF) flew its first B-29 combat mission against targets in Bangkok, Thailand. This mission (longest of the war to date) called for 100 B-29s but only 80 reached the target area. The AAF lost no aircraft to enemy action but bombing results were mediocre. The first bombing mission against the Japanese main islands since Lt. Col. "Jimmy" Doolittle’s raid against Tokyo in April 1942, occurred on June 15, again with poor results. This was also the first mission launched from airbases in China.

With the fall of Saipan, Tinian, and Guam in the Mariana Islands chain in August 1944, the AAF acquired airbases that lay several hundred miles closer to mainland Japan. Late in 1944, the AAF moved the XXI Bomber Command, flying B-29s, to the Marianas and the unit began bombing Japan in December. However, they employed high-altitude, precision, bombing tactics that yielded poor results. The high altitude winds were so strong that bombing computers could not compensate and the weather was so poor that rarely was visual target acquisition possible at high altitudes. In March 1945, Major General Curtis E. LeMay ordered the group to abandon these tactics and strike instead at night, from low altitude, using incendiary bombs. These firebombing raids, carried out by hundreds of B-29s, devastated much of Japan’s industrial and economic infrastructure. Yet Japan fought on. Late in 1944, AAF leaders selected the Martin assembly line to produce a squadron of B-29s codenamed SILVERPLATE. Martin modified these Superfortresses by removing all gun turrets except for the tail position, removing armor plate, installing Curtiss electric propellers, and modifying the bomb bay to accommodate either the "Fat Man" or "Little Boy" versions of the atomic bomb. The AAF assigned 15 Silverplate ships to the 509th Composite Group commanded by Colonel Paul Tibbets. As the Group Commander, Tibbets had no specific aircraft assigned to him as did the mission pilots. He was entitled to fly any aircraft at any time. He named the B-29 that he flew on 6 August Enola Gay after his mother. In the early morning hours, just prior to the August 6th mission, Tibbets had a young Army Air Forces maintenance man, Private Nelson Miller, paint the name just under the pilot’s window.

Enola Gay is a model B-29-45-MO, serial number 44-86292. The AAF accepted this aircraft on June 14, 1945, from the Martin plant at Omaha (Located at what is today Offut AFB near Bellevue), Nebraska. After the war, Army Air Forces crews flew the airplane during the Operation Crossroads atomic test program in the Pacific, although it dropped no nuclear devices during these tests, and then delivered it to Davis-Monthan Army Airfield, Arizona, for storage. Later, the U. S. Air Force flew the bomber to Park Ridge, Illinois, then transferred it to the Smithsonian Institution on July 4, 1949. Although in Smithsonian custody, the aircraft remained stored at Pyote Air Force Base, Texas, between January 1952 and December 1953. The airplane’s last flight ended on December 2 when the Enola Gay touched down at Andrews Air Force Base, Maryland. The bomber remained at Andrews in outdoor storage until August 1960. By then, concerned about the bomber deteriorating outdoors, the Smithsonian sent collections staff to disassemble the Superfortress and move it indoors to the Paul E. Garber Facility in Suitland, Maryland.

The staff at Garber began working to preserve and restore Enola Gay in December 1984. This was the largest restoration project ever undertaken at the National Air and Space Museum and the specialists anticipated the work would require from seven to nine years to complete. The project actually lasted nearly two decades and, when completed, had taken approximately 300,000 work-hours to complete. The B-29 is now displayed at the National Air and Space Museum, Steven F. Udvar-Hazy Center.
