A large amount of aircraft drawings made by North American Aviation are being preserved and put online by AirCorps Aviation.

Those drawings are for warbirds such as the P-51, B-25, T-6 and P-82. They were kept by Ken Jungeberg who had saved the drawings from destruction in 1988. Those drawings languished in a hangar in Ohio until December 2019 when Jungeberg agreed to transfer them to AirCorps.
