Two U.S. Air Force F-16 jet fighters collided and crashed during a training mission over central Spain’s Cuenca province, and one pilot was missing and feared dead, military officials said. A second pilot survived. Air Force Capt. Willette Parker said the jets had taken off from Torrejon Air Base. She identified the pilot who parachuted to safety as Capt. Steven Kempf, 27, of Glendale, Ariz. He was examined by Air Force doctors and released from Torrejon base hospital. She said the identity of the second pilot was not available.
