As displayed in the terminal building at KCMH. Built in Columbus in 1940; despite the what the c/n may suggest, this was not the first Cadet to fly. That was NX20946, c/n 101. The discrepancy requires further research, but my understanding at the moment is that c/n 100 was a development aircraft of some sort. This is reinforced by the fact that the reg "NX20989" is still faintly visible on the underwing and tail fabric. Has since been removed from this location, first to the Historical Aircraft Squadron Museum at LHQ, and then in 2019 to storage with the Ohio History Connection in Columbus.
