NTSB Reports

摘要

At about 0842 Eastern time, the two airplanes were destroyed in an in-flight collision. The airline transport pilot flying the Cessna and the airline transport pilot flying the Grumman were both fatally injured. Visual conditions prevailed. The airplanes were part of a five-ship formation flight. Shortly after establishing their initial V-shaped formation, the flight leader called for changing to a left echelon formation. In this formation, the airplanes are arranged diagonally to the flight leader's left, with each airplane being stacked slightly low, behind, and to the left of the airplane ahead. To accomplish this evolution, the Grumman remained in its position slightly left and behind the leader, while the Cessna and the other two airplanes shifted. The Cessna was to be the number three aircraft, immediately to the left of the Grumman.
