"The Cessna 172RG with the student and instructor left Gillespie Field
in El Cajon first, and the second plane took off about a minute later
from the same airport. The crash occurred about three miles away at an
altitude of 2,300 feet.

Dunks said the student pilot was flying under instrument flight rules,
learning how to control the plane in inclement weather."

"Kupiec, the pilot of the other plane [a Cessna 182], had started
flying from Montgomery Field and stopped off at Gillespie Field before
resuming his flight."

"The plane with the pilot and instructor had filed a flight plan
indicating they were heading south toward Brown Field. The other plane
had contacted the tower on takeoff, but the pilot's destination was
unknown."

"The Cessna 172RG was owned by Scandinavian Aviation Academy, a flight
school based at Gillespie Field. Officials at the school refused to
talk to reporters."
