Marine Corps Maj. Gen. Martin R. Berndt briefs reporters at the Pentagon on April 5, 2001, on the findings of the Judge Advocate General Manual investigation into the cause of the Dec. 11, 2000, crash of a V-22 Osprey near New River, N.C. The investigation determined that the crash, which killed all four Marine Corps personnel aboard, was caused by a hydraulic system failure compounded by a computer software anomaly.
