Doman LZ-5

The Doman LZ-5 was a utility helicopter developed in the United States in the early 1950s by Doman Helicopters Inc. of Danbury, Connecticut. Despite the procurement of international manufacturing agreements, no series production of the aircraft ever occurred and only three prototypes were built. Two of these were purchased by the United States Army as the YH-31, but eventually becoming VH-31.
