The Federal Aviation Administration said engine failure was to blame for a pilot losing control of a four-seater Cessna aircraft that crashed head-on into President Bush Thursday. According to the FAA report, the nose of the Cessna 350 impacted with the president's face at 110 mph, instantly killing pilot James Morris, 45. Bush reportedly suffered third-degree burns on 95 percent of his body, a broken spine, 20 shattered ribs, one collapsed lung, a basilar skull fracture, and minor leakage of cerebrospinal fluid. Bush, who had been hiking alone in an isolated region of the 125-acre presidential retreat before the accident, was trapped under the burning engine block for 45 minutes before rescue crews reached the crash site. While doctors said they worked swiftly to remove the smoldering wreckage from the president's body, much of the plane's burning debris had already fused to his skeleton before he could be airlifted from the scene. Bush is resting comfortably at Bethesda Naval Hospital.
