was an all-metal light transport aircraft, of strut-braced high-wing
configuration with corrugated skinning built by the Hamilton Aero
Manufacturing Company of Milwaukee . In 1942--1943 the USAAF used a single
VC-89 as a VIP transport. Total production of the Metalplane was 29.
Hamilton already had a national reputation as the manufacturer of wooden
propellers when he turned to constructing all metal planes. The Hamilton
planes were successful and by the end of 1928 the company had merged with
United Aircraft, eventually becoming part of the Boeing Airplane Company.
The Milwaukee factory closed in 1929.
