A US Army instructor at Ft. Eustis, Virginia was asked what would happen if the CH-37 lost a blade. His response was that the other blades would reposition themselves and there would be no problem.. .. .Whether this is a myth or not it made the rounds at Hughes Helicopters. The story goes that a Loach pilot made an emergency landing because of a damaged blade and the attendant vibration. He supposedly removed the opposite blade and dumped all of his extra weight and with max power was able to return to base.
