Document 2: Northrop JB-1 Bat: The Northrop JB-1 "Bat" was a United States surface-to-surface cruise missile that was a prototype jet-powered flying wing. The United States Army Air Forces MX-543 program was initiated in September 1942 to use US versions of Frank Whittle's jet engine (US-named General Electric J31). The Northrop Corporation was contracted in late 1943, and only 10 JB-1 airframes were built. A manned version was towed for the 1st flight on "August 27, 1943", ["sic"] from Rogers Dry Lake; and a glider version was launched from a rocket-propelled sled and crashed in December 1944. An unmanned JB-1 powered by an improvised General Electric B-1 turbojet with a wing span of 28 ft made its 1st flight from Eglin Field's Santa Rosa Island, Florida, on December 7, 1944, and crashed 400 yards from the rail launcher.
Document 3: List of surviving Boeing B-17 Flying Fortresses: The Boeing B-17 Flying Fortress is a four-engine heavy bomber aircraft primarily employed by the United States Army Air Forces (USAAF) during World War II. Developed by Boeing, a total of 12,731 aircraft had been produced by Boeing, Douglas and Lockheed from 1936 until 1945. Over 8,000 were lost in either combat operations or training accidents. The remaining combat veterans and early production models were stored and later scrapped in the vast scrap drives of the late 1940s, many going to aircraft boneyards like Davis-Monthan Air Force Base in Tucson, Arizona, the largest of its kind within the United States' borders.
Document 4: 343d Wing: The 343d Wing is an inactive United States Air Force unit. Its last assignment was with Pacific Air Forces at Eielson Air Force Base, Alaska, where it was inactivated on 20 August 1993. The unit was formed at Eielson as the 343d Composite Wing and activated in October 1981 to replace the 5010th Combat Support Group. It operated both fighter and forward air control aircraft. In 1991, it also became the administrator for periodic Exercise Cope Thunder operations, which moved to Alaska from the Philippines after the eruption of Mount Pinatubo resulted in the evacuation of units from Clark Air Base When the wing was inactivated, it was replaced at Eielson by the 354th Fighter Wing.
Document 5: Joint Base Elmendorf–Richardson: Joint Base Elmendorf–Richardson (IATA: EDF, ICAO: PAED, FAA LID: EDF) , or J-BER as it is known to most military members, is a United States military facility in Anchorage, the largest city in Alaska. It is an amalgamation of the United States Air Force's Elmendorf Air Force Base and the United States Army's Fort Richardson, which were merged in 2010.
Document 6: Convair B-36 Peacemaker: The Convair B-36 "Peacemaker" was a strategic bomber built by Convair and operated solely by the United States Air Force (USAF) from 1949 to 1959. The B-36 is the largest mass-produced piston-engined aircraft ever built. It had the longest wingspan of any combat aircraft ever built, at 230 ft (70.1 m). The B-36 was the first bomber capable of delivering any of the nuclear weapons in the U.S. arsenal from inside its four bomb bays without aircraft modifications. With a range of 10000 mi and a maximum payload of 87,200 lb , the B-36 was capable of intercontinental flight without refuelling.
Document 7: Sitka Seaplane Base: Sitka Seaplane Base (FAA LID: A29) is a public use seaplane base owned by and located in Sitka, a city and borough in the U.S. state of Alaska. It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a "general aviation" facility. This seaplane base is located near the Sitka Rocky Gutierrez Airport.
Document 8: Operation Snow Flurry: Operation Snow Flurry was an operation by the United States Air Force that consisted of B-47 Stratojet bombers flying to England to perform mock bomb drops. Data would be received on the ground from the planes, and this would later be used to track the accuracy of the mock drops. In 1958, a B-47 en route from Hunter Air Force Base accidentally dropped an inert Mark 6 nuclear bomb over Mars Bluff, South Carolina, although the explosion damaged nearby buildings. Live bombs were carried on board in case the planes had to activate for a wartime situation, but had their fissile nuclear cores removed and couldn't cause a nuclear detonation.
Document 9: K. I. Sawyer Air Force Base: K. I. Sawyer Air Force Base is a decommissioned U.S. Air Force installation in Marquette County, Michigan, south of the city of Marquette. Near the center of Michigan's Upper Peninsula, the base operated for nearly forty years and closed in 1995. The county airport, Sawyer International, now occupies a portion of the base and has scheduled airline flights and some general aviation activity. The area of the former base is now an unincorporated community and a census-designated place for statistical purposes known as K. I. Sawyer AFB
Document 10: Elmendorf Air Force Base: Elmendorf Air Force Base (IATA: EDF, ICAO: PAED, FAA LID: EDF) is a United States military facility in Anchorage, the largest city in Alaska.

Document 11: Enola Gay: The Enola Gay ( ) is a Boeing B-29 Superfortress bomber, named for Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets, who selected the aircraft while it was still on the assembly line. On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb. The bomb, code-named "Little Boy", was targeted at the city of Hiroshima, Japan, and caused unprecedented destruction. "Enola Gay" participated in the second atomic attack as the weather reconnaissance aircraft for the primary target of Kokura. Clouds and drifting smoke resulted in a secondary target, Nagasaki, being bombed instead.

It was established in 1943 as Mile 26 Satellite Field and taken off deployment in 2007. It has been a Superfund site since 1989.
Document 13: Bockscar: Bockscar, sometimes called Bock's Car, is the name of the United States Army Air Forces B-29 bomber that dropped a Fat Man nuclear weapon over the Japanese city of Nagasaki during World War II in the second – and last – nuclear attack in history. One of 15 Silverplate B-29s used by the 509th, "Bockscar" was built at the Glenn L. Martin Aircraft Plant at Bellevue, Nebraska, at what is now Offutt Air Force Base, and delivered to the United States Army Air Forces on 19 March 1945. It was assigned to the 393d Bombardment Squadron, 509th Composite Group to Wendover Army Air Field, Utah in April.

This was the first such nuclear weapon loss in history. The B-36 had been en route from Eielson Air Force Base near Fairbanks, Alaska to Carswell AFB in Fort Worth, Texas, more than 3000 miles south-east, on a mission that included a simulated nuclear attack on San Francisco.
