An Air Force fighter pilot was killed after his jet and another likely collided during a training exercise and crashed into the Gulf of Mexico. The other pilot was rescued and is expected to survive, AP reported. The single-seat F-15C Eagles crashed Wednesday off northern Florida, said Col. Todd Harmer, commander of the 33rd Fighter Wing, 58th Fighter Squadron. The pilots had ejected and were later rescued. The cause of the collision about 35 miles (55 kilometers) south of Tyndall Air Force Base on the Gulf Coast of Florida, was not immediately known, but the Air Force will investigate, Harmer said. Weather in the area was clear. A Coast Guard rescue jet located one pilot and radioed the location to a fishing vessel, which picked him up, said Coast Guard Petty Officer James Harless. A Coast Guard helicopter then hoisted the pilot off the vessel. That pilot told rescuers he saw the other pilot also eject but lost sight of him in the clouds, Harless said. He told them the approximate location for the second pilot, who was found by a Coast Guard helicopter, Harless said.
