The I-X Center's KC-97G-24-BO (S/N 52-2604) was built in Seattle, Washington, in 1953 and served at U.S. Air Force and National Guard bases across the country and in Germany. It was retired in 1978 and was shipped to the Military Aircraft Storage and Disposition Center at the Davis-Monthan Air Force Base in Arizona.
Boeing KC-97G Stratofreighter
The KC-97 Stratofreighter was an aerial refueling tanker variant of the C-97 Stratofreighter, which was itself based on the Boeing B-29 Superfortress. It was modified with fuel tanks, plumbing, and a flying boom. The cavernous upper deck was capable of accommodating oversize cargo accessed through a very large right-side door. In addition, transferable jet fuel was contained in tanks on the lower deck (G-L models). Both decks were heated and pressurized for high altitude operations.
