Christie's Last Chance
Christie received some funds to develop his airborne tank after a relative success in Britain. The tank was converted into the M1938 tank, which didn't have much luck with the American military either. Christie, experiencing major financial troubles, sold his company to William J. Bigley and his United States Convertible Systems Inc.
The situation changed in early 1941. The British, who were planning on mass purchases of American tanks, were interested in an airborne tank. The Americans immediately remembered Christie and his wonder-machines. In late 1941, the Christie M1936 airborne tank was tested at the Aberdeen proving grounds. During the trials, the vehicle broke down constantly, but showed impressive characteristics. The report referred to it as "Bigley-Christie".
