Jonathan Edward Caldwell - Another Autogyro

Another Autogyro

In 1939 Caldwell shut down Grey Goose and swapped shares once again, forming Rotor Planes, Inc. His latest design retained the disk-rotor from his earlier autogyro, but replaced the fuselage with a smaller disk in the center. According to some accounts, around 1940 the Maryland securities commission also started examining Caldwell, who promptly disappeared, abandoning the broken disk-rotor and the partially completed rotorplane.
