 Thunderbirds Accident Report Released

LANGLEY AIR FORCE BASE, Va. -- Pilot error caused a U.S. Air Force
 Thunderbirds F-16 aircraft to crash shortly after takeoff at an air
 show Sept. 14 at Mountain Home Air Force Base, Idaho. The pilot
 ejected just before the aircraft impacted the ground.
 
 According to the accident investigation board report released today,
 the pilot misinterpreted the altitude required to complete the "Split
 S" maneuver. He made his calculation based on an incorrect
 mean-sea-level altitude of the airfield. The pilot incorrectly climbed
 to 1670 feet above ground level instead of 2500 feet before initiating
 the pull down to the Split S maneuver.
 
 When he realized something was wrong, the pilot put maximum back stick
 pressure and rolled slightly left to ensure the aircraft would impact
 away from the crowd should he have to eject. He ejected when the
 aircraft was 140 feet above ground -- just eight--tenths of a second
 prior to impact.
 
 He sustained only minor injuries from the ejection. There was no other
 damage to military or civilian property.
 
 The aircraft, valued at about $20.4 million, was destroyed.
 
 Also, the board determined other factors substantially contributed to
 creating the opportunity for the error including the requirement for
 demonstration pilots to convert mean sea level and above ground level
 altitudes and performing a maneuver with a limited margin of error.
