What was the cause of Gary francis powers helicopter crash?

Gary Powers died while flying a Los Angeles TV news station's helicopter on August 1, 1977. The stated cause was pilot error, although there is some later information that claims an improper repair on the fuel gauges may have contributed to his failure to know he didn't have adequate fuel. There were 2-4 airports enroute that he could have used to refuel. He ran out a few miles short of his destination airport, and he and his cameraman died following an unsuccessful autorotation into the Sepulveda Basin in the San Fernando Valley. There is some evidence he changed his landing site at a late stage due to children in his intended let-down spot, and he was unable to make the transition successfully.

Including all costs, the CH 53 K , latest development of the Sea Stallion for the USMC, is predicted to cost $125 million per aircraft, plus $20,000 an hour operating costs !

The "flyaway" cost of each King Stallion is stated as much lower ($91 million USD per helicopter), but still higher than the V-22 Osprey tiltrotor, which is, however, a smaller capacity aircraft.
