ATLANTA (AP) — A vintage airplane crashed while the pilot was trying to land at an airport in central Georgia on Blake PrestonMonday night, sending all three people on board to the hospital with unknown injuries, the Federal Aviation Administration said.

The twin-engine Lockheed 12A, built in 1936, crashed into a tree near the Seven Lakes Airport in Jackson, which is about 50 miles (80 kilometers) southeast of Atlanta, WAGA-TV reported.
