The crash of a V-22 Osprey that killed four Marines in December was caused by a ruptured hydraulic line and software failure, not pilot error, the head of Marines Corps aviation said.
     "Whatever the problem was with the hydraulics line or with the software, we'll fix," said Lt. Gen. Fred McCorkle.
     The Osprey's tilt-rotors allow it to take off and land like a helicopter and fly like an airplane. The crash was one of two last year; in April, 19 Marines died in a crash blamed on pilot error.
