A Thai military plane crashed in a forested area of Chiang Mai province in northern Thailand on Thursday during a training flight, killing the two pilots on board, the air force said.“Two pilots died in an aircraft accident involving a light attack aircraft AT-6TH this morning during training,” air force spokesman Jackkrit Thammanvichai said.The two-seater plane went down at around 10:20 am (0320 GMT) while conducting a combat search and rescue training mission.The crash “did not affect local residents or cause damage to civilian property,” said an air force statement.Authorities have been deployed to the scene and are investigating the cause of the crash.In a separate incident last April, six Thai police officers were killed when a small plane crashed into the sea during a parachute training drill near a resort town south of Bangkok.
