The Thunderbirds pilot who crashed and died in April apparently lost consciousness before the crash.
The 37-page Air Force Aircraft Accident Investigation Board report says that Maj. Stephen "Cajun" Del Bagno was conducting a maneuver called "High Bomb Burst Rejoin" that led to a half-loop or Split-S maneuver.
A sudden change in G-forces resulted in Del Bagno passing out.
A range safety officer and another pilot tried to reach the major on his radio before he crashed on the Test Range near Creech Air Force Base in Indian Springs.
