1965 – 1976 Lancia Fulvia Coupé

Image by Georg Sander
The Lancia Fulvia is an Italian auto introduced at the Geneva Motor Show in 1963 by Lancia. It was made by that company by means of 1976. Fulvias are notable for their role in automobile racing history, including winning the International Rally Championship in 1972. On testing it in 1967, Road &amp Track summed up the Fulvia as &quota precision motorcar, an engineering tour de force&quot.

Der Lancia Fulvia ist ein Automobil des italienischen Herstellers Lancia. Es wurde von Herbst 1963 bis Ende 1976 gebaut und gilt als Nachfolgemodell des Lancia Appia.

Wie andere nach dem 1950 vorgestellten Aurelia entwickelten Lancia-Modelle war der Fulvia nach einer klassischen Römerstraße, hier der Via Fulvia, benannt. Im Herbst 1972 wurde dieses Method der Benennung wieder geändert: der unter Fiat-Regie gebaute Nachfolger des Fulvia war der Lancia Beta.

Der Fulvia war als Berlina (Limousine) und als Coupé erhältlich. Außerdem gab es wie bei Lancia üblich ein bei Carrozzeria Zagato entworfenes und in Kleinserie gebautes Fließheckcoupé mit dem traditionellen Namen Sport. Das technische Konzept des Fulvia stammt von Antonio Fessia, die Type wurde von Pietro Castagnero bei Lancia entworfen.

PA – Mill Run: Fallingwater – Living space fireplace and kettle

Image by wallyg
A boulder best, increasing unaltered above the level of the very first floor, serves as the hearth of the 1,800-square-foot living area fireplace and the functional and spiritual heart of Fallingwater. To the left hangs a spherical Cherokee-red kettle that can be swung over the fire. The kettle, copied soon after one Frank Lloyd Wright utilised at Taliesin, was intended to serve mulled wine, but proved unworkable. The fireplace fork is signed by the master ironworker Samuel Yellin, who created it about 1930 for La Tourelle.

Fallingwater, often referred to as the Edgar J. Kaufmann Sr. Residence or just the Kaufmann Residence, situated inside a five,100-acre nature reserve 50 miles southeast of Pittsburgh, was developed by Frank Lloyd Wright and constructed amongst 1936 and 1939. Built more than a 30-foot flowing waterfall on Bear Run in the Mill Run section of Stewart Township, Fayette County, Pennsylvania, the property served as a vacation retreat for the Kaufmann loved ones like patriarch, Edgar Kaufmann Sr., was a productive Pittsburgh businessman and president of Kaufmann’s Department Shop, and his son, Edgar Kaufmann, Jr., who studied architecture briefly below Wright. Wright collaborated with employees engineers Mendel Glickman and William Wesley Peters on the structural design and style, and assigned his apprentice, Robert Mosher, as his permanent on-internet site representative throughout building. Despite frequent conflicts between Wright, Kaufmann, and the building contractor, the home and guesthouse were lastly constructed at a cost of 5,000.

Fallingwater was designated a National Historic Landmark in 1966. It was listed among the Smithsonian’s 28 Areas to See Prior to You Die. In a 1991 poll of members of the American Institute of Architects (AIA), it was voted &quotthe very best all-time work of American architecture.&quot In 2007, Fallingwater was ranked #29 on the AIA 150 America’s Favorite Architecture list.

Image by Chris Devers
Quoting Smithsonian National Air and Space Museum | Vought OS2U-3 Kingfisher:

The Kingfisher was the U.S. Navy’s principal ship-primarily based, scout and observation aircraft during Globe War II. Revolutionary spot welding methods gave it a smooth, non-buckling fuselage structure. Deflector plate flaps that hung from the wing’s trailing edge and spoiler-augmented ailerons functioned like further flaps to enable slower landing speeds. Most OS2Us operated in the Pacific, where they rescued a lot of downed airmen, like World War I ace Eddie Rickenbacker and the crew of his B-17 Flying Fortress.

In March 1942, this airplane was assigned to the battleship USS Indiana. It later underwent a six-month overhaul in California, returned to Pearl Harbor, and rejoined the Indiana in March 1944. Lt. j.g. Rollin M. Batten Jr. was awarded the Navy Cross for creating a daring rescue in this airplane below heavy enemy fire on July four, 1944.

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

No matter whether identified as the Warhawk, Tomahawk, or Kittyhawk, the Curtiss P-40 proved to be a effective, versatile fighter throughout the first half of Globe War II. The shark-mouthed Tomahawks that Gen. Claire Chennault’s &quotFlying Tigers&quot flew in China against the Japanese remain among the most well-known airplanes of the war. P-40E pilot Lt. Boyd D. Wagner became the 1st American ace of World 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 until 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.

Long Description:
Whether or not it was the Tomahawk, Warhawk, or Kittyhawk, the Curtiss P-40 was a effective and versatile fighter aircraft for the duration of the 1st half of Globe War II. The shark-mouthed Tomahawks that General Claire Chennault led against the Japanese remain among the most well-known airplanes of the war. In the Phillipines, Lt. Boyd D. Wagner became the initial American ace of Planet War II whilst flying a P-40E when he shot down six Japanese aircraft in the course of mid-December 1941. P-40s had been first-line Army Air Corps fighters at the begin of the war but they quickly gave way to far more advanced styles such as the Republic P-47 Thunderbolt and the Lockheed P-38 Lightning (see NASM collection for each aircraft). The P-40 is not ranked amongst the very best all round fighters of the war but it was a rugged, effective style obtainable in big numbers early in the war when America and her allies urgently necessary them. The P-40 remained in production from 1939 to the end of 1944 and a total of 13, 737 have been built.

Design engineer Dr. Donovan R. Berlin layed the foundation for the P-40 in 1935 when he created the agile, but lightly-armed, P-36 fighter equipped with a radial, air-cooled engine. The Curtiss-Wright Corporation won a production contract for 210 P-36 airplanes in 1937-the biggest Army airplane contract awarded because World War I. Worldwide, fighter aircraft styles matured rapidly in the course of the late 1930s and it was soon apparent that the P-36 was no match for newer European designs. Higher altitude overall performance in particular became a priceless commodity. Berlin attempted to increase the P-36 by redesigning it in to accommodate a turbo-supercharged Allison V-1710-11 inline, liquid-cooled engine. The new aircraft was designated the XP-37 but proved unpopular with pilots. The turbo-supercharger was not trustworthy and Berlin had placed the cockpit as well far back on the fuselage, restricting the view to the front of the fighter. Nonetheless, when the engine was not giving difficulty, the more-streamlined XP-37 was a lot more quickly than the P-36.

Curtiss attempted once more in 1938. Berlin had modified yet another P-36 with a new Allison V-1710-19 engine. It was designated the XP-40 and very first flew on October 14, 1938. The XP-40 looked promising and Curtiss supplied it to Army Air Corps leaders who evaluated the airplane at Wright Field, Ohio, in 1939, along with numerous other fighter proposals. The P-40 won the competitors, soon after some modifications, and Curtiss received an order for 540. At this time, the armament package consisted of two .50 caliber machine guns in the fuselage and 4 .30 caliber machine guns in the wings.

After production began in March 1940, France ordered 140 P-40s but the British took delivery of these airplanes when Paris surrendered. The British named the aircraft Tomahawks but identified they performed poorly in higher-altitude combat over northern Europe and relegated them to low-altitude operations in North Africa. The Russians bought much more than 2,000 P-40s but information of their operational history stay obscure.

When the United States declared war, P-40s equipped numerous of the Army Air Corps’s front line fighter units. The plucky fighter ultimately saw combat in practically each and every theater of operations being the most powerful in the China-Burma-India (CBI) Theater. Of all the CBI groups that gained the most notoriety of the complete war, and remains to this day synonymous with the P-40, is the American Volunteer Group (AVG) or the Flying Tigers. The unit was organized right after the Chinese gave former U. S. Army Air Corps Captain Claire Lee Chennault virtually 9 million dollars in 1940 to buy aircraft and recruit pilots to fly against the Japanese. Chennault’s most critical assistance within the Chinese government came from Madam Chiang Kai-shek, a Lt. Colonel in the Chinese Air Force and for a time, the service’s overall commander.

The income from China diverted an order placed by the British Royal Air Force for one hundred Curtiss-Wright P-40B Tomahawks but getting airplanes was only one particular important step in making a fighting air unit. Educated pilots had been required, and rapidly, as tensions across the Pacific escalated. On April 15, 1941, President Franklin D. Roosevelt quietly signed an Executive Order permitting Chennault to recruit straight from the ranks of American military reserve pilots. Within a few months, 350 flyers joined from pursuit (fighter), bomber, and patrol squadrons. In all, about half the pilots in the Flying Tigers came from the U. S. Navy and Marine Corps even though the Army Air Corps supplied 1-third. Factory test pilots at Bell, Consolidated, and other firms, and commercial airline pilots, filled the remaining slots.

The Flying Tigers flew their 1st mission on December 20. The unit’s name was derived from the ferocious fangs and teeth painted on the nose of AVG P-40s at either side of the distinctive, large radiator air intake. The concept is mentioned to originate from images in a magazine that showed Royal Air Force Tomahawks of No. 112 Squadron, operating in the western desert of North Africa, adorned with fangs and teeth painted about their air intakes. The Flying Tigers had been the first genuine opposition the Japanese military encountered. In much less than 7 months of action, AVG pilots destroyed about 115 Japanese aircraft and lost only 11 planes in air-to-air combat. The AVG disbanded on July four, 1942, and its assets, which includes a few pilots, became a component of the U. S. Army Air Forces (AAF) 23rd Fighter Group in the newly activated 14th Air Force. Chennault, now a Brigadier Common, assumed command of the 14th AF and by war’s end, the 23rd was one of the highest-scoring Army fighter groups.

As wartime expertise in the P-40 mounted, Curtiss made several modifications. Engineers added armor plate, greater self-sealing fuel tanks, and far more potent engines. They modified the cockpit to enhance visibility and changed the armament package to six, wing-mounted, .50 caliber machine guns. The P-40E Kittyhawk was the very first model with this gun package and it entered service in time to serve in the AVG. The last model created in quantity was the P-40N, the lightest P-40 constructed in quantity, and significantly more quickly than preceding models. Curtiss constructed a single P-40Q. It was the quickest P-40 to fly (679 kph/422 mph) but it could not match the functionality of the P-47 Thunderbolt and the P-51 Mustang so Curtiss ended development of the P-40 series with this model. In addition to the AAF, several Allied nations purchased and flew P-40s like England, France, China, Russia, Australia, New Zealand, Canada, South Africa, and Turkey.

The Smithsonian P-40E did not serve in the U. S. military. Curtiss-Wright built it in Buffalo, New York, as Model 87-A3 and delivered it to Canada as a Kittyhawk IA on March 11, 1941. It served in No. 111 Squadron, Royal Canadian Air Force (RCAF). When the Japanese navy moved to attack Midway, they sent a diversionary battle group to menace the Aleutian Islands. Canada moved No. 111 Squadron to Alaska to assist defend the region. Right after the Japanese threat diminished, the unit returned to Canada and at some point transferred to England without having its P-40s. The RCAF declared the NASM Kittyhawk IA surplus on July 27, 1946, and the aircraft at some point returned to the United States. It had several owners prior to ending up with the Explorer Scouts youth group in Meridian, Mississippi. Throughout the early 1960s, the Smithsonian started looking for a P-40 with a documented history of service in the AVG but discovered none. In 1964, the Exchange Club in Meridian donated the Kittyhawk IA to the National Aeronautical Collection, in memory of Mr. Kellis Forbes, a local man devoted to Boys Club activities. A U. S. Air Force Reserve crew airlifted the fighter to Andrews Air Force Base, Maryland, on March 13, 1964. Andrews personnel restored the airplane in 1975 and painted it to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Quoting from Wikipedia | Curtiss P-40 Warhawk:

The Curtiss P-40 Warhawk was an American single-engine, single-seat, all-metal fighter and ground attack aircraft that 1st flew in 1938. It was employed by the air forces of 28 nations, such as these of most Allied powers in the course of World War II, and remained in front line service till the finish of the war. It was the third most-made American fighter, following the P-51 and P-47 by November 1944, when production of the P-40 ceased, 13,738 had been constructed, all at Curtiss-Wright Corporation‘s primary production facility at Buffalo, New York.

The P-40 design and style was a modification of the preceding Curtiss P-36 this lowered improvement time and enabled a speedy entry into production and operational service.

Warhawk was the name the United States Army Air Corps adopted for all models, generating it the official name in the United States for all P-40s. The British Commonwealth and Soviet air forces utilised the name Tomahawk for models equivalent to the P-40B and P-40C, and the name Kittyhawk for models equivalent to the P-40D and all later variants.

The P-40’s lack of a two-stage supercharger produced it inferior to Luftwaffe fighters such as the Messerschmitt Bf 109 or the Focke-Wulf Fw 190 in high-altitude combat and it was rarely utilized in operations in Northwest Europe. In between 1941 and 1944, however, the P-40 played a crucial role with Allied air forces in three main theaters: North Africa, the Southwest Pacific and China. It also had a considerable role in the Middle East, Southeast Asia, Eastern Europe, Alaska and Italy. The P-40’s functionality at high altitudes was not as crucial in those theaters, where it served as an air superiority fighter, bomber escort and fighter bomber.

P-40s 1st saw combat with the British Commonwealth squadrons of the Desert Air Force (DAF) in the Middle East and North African campaigns, in the course of June 1941. The Royal Air Force‘s No. 112 Squadron was amongst the first to operate Tomahawks, in North Africa, and the unit was the initial to feature the &quotshark mouth&quot logo, copying related markings on some Luftwaffe Messerschmitt Bf 110 twin-engine fighters. [N 1]

Even though it gained a post-war reputation as a mediocre design, appropriate only for close air assistance, much more current analysis like scrutiny of the records of individual Allied squadrons indicates that the P-40 performed surprisingly properly as an air superiority fighter, at instances suffering extreme losses, but also taking a extremely heavy toll on enemy aircraft. The P-40 supplied the further benefit of low cost, which kept it in production as a ground-attack fighter extended following it was obsolete in the air superiority function.

As of 2008, 19 P-40s were airworthy.

Specifics, quoting from Smithsonian National Air and Space Museum | Boeing B-29 Superfortress &quotEnola Gay&quot:

Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of Globe War II and the very first bomber to house its crew in pressurized compartments. Despite the fact that developed to fight in the European theater, the B-29 located its niche on the other side of the globe. In the Pacific, B-29s delivered a range of aerial weapons: traditional bombs, incendiary bombs, mines, and two nuclear weapons.

On August six, 1945, this Martin-built B-29-45-MO dropped the very first atomic weapon employed in combat on Hiroshima, Japan. 3 days later, Bockscar (on display at the U.S. Air Force Museum close to 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 Wonderful Artiste, flew as an observation aircraft on each missions.

Extended Description:
Boeing’s B-29 Superfortress was the most sophisticated, propeller-driven, bomber to fly during World War II, and the initial bomber to home its crew in pressurized compartments. Boeing installed extremely sophisticated armament, propulsion, and avionics systems into the Superfortress. For the duration of the war in the Pacific Theater, the B-29 delivered the initial nuclear weapons utilised in combat. On August 6, 1945, Colonel Paul W. Tibbets, Jr., in command of the Superfortress Enola Gay, dropped a extremely enriched uranium, explosion-type, &quotgun-fired,&quot atomic bomb on Hiroshima, Japan. Three days later, Major Charles W. Sweeney piloted the B-29 Bockscar and dropped a hugely enriched plutonium, implosion-variety atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance climate 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 want for extremely lengthy-variety bombers that exceeded the performance of the B-17 Flying Fortress. Numerous years of preliminary studies paralleled a continuous fight against these who saw restricted utility in creating such an costly 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 eight,050 km (5,000 miles). Boeing, Consolidated, Douglas, and Lockheed responded with design and style 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 yet another contract for 250 aircraft plus spare parts equivalent to an additional 25 bombers, eight months prior to Pearl Harbor and nearly a year-and-a-half prior to the very first Superfortress would fly.

Among the design’s innovations was a extended, narrow, higher-aspect ratio wing equipped with big Fowler-variety flaps. This wing style allowed the B-29 to fly extremely fast at high altitudes but maintained comfortable handling characteristics throughout takeoff and landing. Far 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 a lot far more comfortable as stress and temperature could be regulated. To protect the Superfortress, Boeing created a remote-controlled, defensive weapons method. Engineers placed 5 gun turrets on the fuselage: a turret above and behind the cockpit that housed two .50 caliber machine guns (4 guns in later versions), and an additional turret aft close to the vertical tail equipped with two machine guns plus two more turrets beneath the fuselage, each and every 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. One more two .50 caliber machine guns and a 20-mm cannon (in early versions of the B-29) had been fitted in the tail beneath the rudder. Gunners operated these turrets by remote manage–a accurate innovation. They aimed the guns utilizing computerized sights, and each and every gunner could take handle of two or a lot more turrets to concentrate firepower on a single target.

Boeing also equipped the B-29 with advanced radar gear and avionics. Based on the sort of mission, a B-29 carried the AN/APQ-13 or AN/APQ-7 Eagle radar program to aid bombing and navigation. These systems have been accurate enough to permit bombing by way of cloud layers that completely obscured the target. The B-29B was equipped with the AN/APG-15B airborne radar gun sighting technique mounted in the tail, insuring precise defense against enemy fighters attacking at night. B-29s also routinely carried as a lot of as twenty various varieties of radios and navigation devices.

The initial XB-29 took off at Boeing Field in Seattle on September 21, 1942. By the finish of the year the second aircraft was prepared for flight. Fourteen service-test YB-29s followed as production began to accelerate. Creating this sophisticated bomber essential massive logistics. Boeing constructed new B-29 plants at Renton, Washington, and Wichita, Kansas, even though Bell built a new plant at Marietta, Georgia, and Martin constructed 1 in Omaha, Nebraska. Each Curtiss-Wright and the Dodge automobile firm vastly expanded their manufacturing capacity to construct the bomber’s strong and complicated Curtiss-Wright R-3350 turbo supercharged engines. The system essential thousands of sub-contractors but with extraordinary work, it all came together, despite main teething problems. By April 1944, the initial operational B-29s of the newly formed 20th Air Force started to touch down on dusty airfields in India. By May, 130 B-29s had been operational. In June, 1944, much less than two years following the initial flight of the XB-29, the U. S. Army Air Forces (AAF) flew its initial B-29 combat mission against targets in Bangkok, Thailand. This mission (longest of the war to date) referred to as for 100 B-29s but only 80 reached the target location. The AAF lost no aircraft to enemy action but bombing benefits were mediocre. The very first bombing mission against the Japanese main islands because Lt. Col. &quotJimmy&quot Doolittle’s raid against Tokyo in April 1942, occurred on June 15, once again with poor final results. This was also the initial 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 a number of 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 started bombing Japan in December. However, they employed high-altitude, precision, bombing tactics that yielded poor benefits. The higher altitude winds had been so strong that bombing computers could not compensate and the climate was so poor that rarely was visual target acquisition achievable at high altitudes. In March 1945, Major General Curtis E. LeMay ordered the group to abandon these tactics and strike rather 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 financial infrastructure. But 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 &quotFat Man&quot or &quotLittle Boy&quot 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 following his mother. In the early morning hours, just prior to the August 6th mission, Tibbets had a young Army Air Forces upkeep man, Private Nelson Miller, paint the name just under the pilot’s window.

Enola Gay is a model B-29-45-MO, serial quantity 44-86292. The AAF accepted this aircraft on June 14, 1945, from the Martin plant at Omaha (Positioned at what is today Offut AFB close to Bellevue), Nebraska. Following the war, Army Air Forces crews flew the airplane for the duration of the Operation Crossroads atomic test program in the Pacific, despite the fact that it dropped no nuclear devices for the duration of 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 four, 1949. Even though 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 outside storage till 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 functioning to preserve and restore Enola Gay in December 1984. This was the biggest restoration project ever undertaken at the National Air and Space Museum and the specialists anticipated the operate would call for from seven to nine years to total. The project in fact lasted nearly two decades and, when completed, had taken roughly 300,000 work-hours to complete. The B-29 is now displayed at the National Air and Space Museum, Steven F. Udvar-Hazy Center.

Quoting Smithsonian National Air and Space Museum | Lockheed P-38J-10-LO Lightning :

In the P-38 Lockheed engineer Clarence &quotKelly&quot Johnson and his team of designers created one of the most productive twin-engine fighters ever flown by any nation. From 1942 to 1945, U. S. Army Air Forces pilots flew P-38s more than Europe, the Mediterranean, and the Pacific, and from the frozen Aleutian Islands to the sun-baked deserts of North Africa. Lightning pilots in the Pacific theater downed much more Japanese aircraft than pilots flying any other Allied warplane.

Maj. Richard I. Bong, America’s leading fighter ace, flew this P-38J-10-LO on April 16, 1945, at Wright Field, Ohio, to evaluate an experimental method of interconnecting the movement of the throttle and propeller manage levers. Even so, his correct engine exploded in flight before he could conduct the experiment.

Quoting Smithsonian National Air and Space Museum | Boeing B-29 Superfortress &quotEnola Gay&quot:

Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of World War II and the initial bomber to home its crew in pressurized compartments. Even though created to fight in the European theater, the B-29 located its niche on the other side of the globe. In the Pacific, B-29s delivered a range of aerial weapons: conventional bombs, incendiary bombs, mines, and two nuclear weapons.

On August six, 1945, this Martin-built B-29-45-MO dropped the very first atomic weapon utilised in combat on Hiroshima, Japan. Three days later, Bockscar (on display at the U.S. Air Force Museum close to 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 each missions.
