PRESCOTT, Ariz. (AP) _ Two stunt planes collided Saturday during a practice session in central Arizona, killing both pilots, authorities said.
``They were out practicing stunts, and it looks like one plane clipped the wing of the other plane,'' said Lt. Steve Francis of the Yavapai County Sheriff's Office.
The planes crashed in a field. There were no other passengers, and no other injuries were reported, Francis said.
Killed were Mike Corradi, 55, and Robert Sweginnis, whose age was not available. Both were from the Prescott area, Francis said.
The single-engine planes were owned by Embry Riddle Aeronautical University, about 100 miles northwest of Phoenix. A message left with Embry Riddle was not immediately returned Saturday.
