It is said that 90,000 people turned out for the XC-99's first flight. This transport derivative of the B-36 bomber never made much sense, and the wheel pressure caused by the original undercarriage even ensured there were very few places it could fly to! Its last flight was on 19 March 1957, following which it was preserved at Kelly AFB in San Antonio, TX. It was acquired by the USAF Museum in 1993, but it took 15 years before the aircraft was actually moved to their main facility in Dayton, OH, in early 2008. In 2012 the disassembled XC-99 was moved again, this time to Davis-Monthan AFB in Arizona for storage. It is said that restoration could take more than 30 years.
