Boeing B-17 (sn. 44–85734)[4] did not see combat in World War II, and was originally sold on 25 June 1947, as scrap to Esperado Mining Co. of Altus, Oklahoma; it was then sold again later that year for $2,700 to Pratt & Whitney, which operated the B-17 as a heavily modified testbed aircraft[1] (similar to B-17s sn. 44-85747 and sn. 44-85813).[5] Following these flights, it was donated to the Connecticut Aeronautical Historic Association, where a tornado on 3 October 1979, blew another aircraft onto the B-17's midsection, breaking the fuselage.
The B-17 was eventually purchased by aviation enthusiast Don Brooks, who formed the Liberty Foundation to exhibit it as the Liberty Belle. Restoration began in 1992 with parts from another damaged B-17 (sn. 44–85813), performed by Tom Reilly and company/Flying Tigers Warbird Restoration Museum (aka "Bombertown USA"), located at that time at Kissimmee Gateway field, Kissimmee, Florida. She returned to the air on 8 December 2004 and had been touring the country offering the public rides on the bomber. The Liberty Foundation also took an historic overseas tour in July 2008 along the northern ferry route to England.
On the morning of 13 June 2011, Liberty Belle made a forced landing in Oswego, Illinois, after taking off from Aurora Municipal Airport in Sugar Grove, Illinois. Shortly after takeoff, the pilot of a North American T-6 Texan being flown as a chase plane informed Liberty Belle's pilot that the B-17's inboard left wing was on fire and advised an immediate landing. The bomber landed successfully in a nearby field and the seven people on board were able to evacuate without injury; but due to the muddy ground in the field, fire engines could not reach it, allowing the fire to spread and destroy the aircraft.[6] The bomber's remains were stored in a hangar in Aurora for a few days before being taken back to its home at Brooks Aviation Inc in Douglas, Georgia. It is currently under rebuild to airworthy status, using the forward fuselage of another B-17 (sn. 44–83387)[7][better source needed] and other new parts, but it is not known when the restoration will be completed.[8]
