Pima Air and Space Museum Aircraft
The HUM-1 is a small two passenger utility helicopter originally designed by the Helicopter Engineering Research Corporation in 1948. The design was taken up by the McCulloch Motors Corporation and offered to the U.S. Army as the XH-30 and to the Navy as the HUM-1. Three were built for the Army and two for the Navy in 1953. Neither service was able to find a use for the tiny helicopters and they were returned to McCulloch. A civil version, the MC-4, was likewise unable to generate any sales and McCulloch lost interest in the project and turned it back over to the original designer D. K. Jovanovich.
