Two Thai Air Force F-16 jet fighters crashed on Monday in Northeastern Thailand during a joint exercise with the US military but neither pilot was injured, an official said.
"A team was sent to investigate the crash. We don't know yet what caused it," Air Vice Marshall Monthon Satchukorn, a spokesman for the Royal Thai Air Force, told AFP.
He said the fighters disappeared from the radar screen during the exercise and were later found by local villagers. The two pilots ejected and were safe.
Local media reports suggested the two planes may have collided but Monthon said it was too early to speculate about what happened.
