Improper Formation Execution Resulted In Collision During
Four-Ship Training Flight
Aircrew error caused a midair collision of two F-15 Eagles off
the coast of Okinawa, Japan, according to an accident investigation
report released January 20.
The aircraft both landed safely and neither pilot was injured.
They were temporarily assigned to the 12th Expeditionary Fighter
Squadron at Kadena Air Base when the aircraft collided during a
training mission October 4.
The board concluded that one of the two pilots involved failed
to maintain the flight formation that had been briefed before
takeoff. It also concluded that errors in both pilots' judgment
were contributing factors.
The collision took
place over open sea about 100 miles south of Okinawa. The two
aircraft involved formed half of a four-ship formation on a
regularly scheduled training mission. During the flight, one of the
involved aircraft banked slightly in the direction of the second,
creating closure that was not recognized by either pilot.
The first aircraft flew into the flight path of the second where
its left wingtip and horizontal stabilizer hit the left and right
vertical stabilizers of the second. Both aircraft were damaged in
