This big "flying crane" built for the US Army's HLH (Heavy Lift Helicopter) specification, was put into storage prior to completion when the programme was cancelled in October 1974. In 1983 plans were initiated to resume the test programme with a possible first flight in 1985. The HLH would be capable of carrying 20 tonnes over a distance of nearly 40km.
