USAF C-7B 62-4182 was moved to the Western International Aviation scrapyard at Davis-Monthan in Sep 1986. It was registered to Newcal Aviation as N60NC on 5 Sep 1986, but this registration was never applied, and the aircraft did not leave the Western scrapyard until 30 Sep 2020 when it was moved from the Western International scrapyard to a compound at the Pima Air & Space Museum, reportedly for a rebuild using parts from 62-4150/N92NC c/n 86 and 63-9739/N80NC c/n 186. It was again registered, now as N68NC, on 15 Jun 2021, but this registration too was never applied to the aircraft. This Caribou was still stored at the museum at the time of upload, with no sign of any rebuild.
