The pilot and two other American personnel were brought to a hospital for treatment after Tuesday afternoon’s incident in a concrete bypass road in Laoac town in the northern Pangasinan province. Two other injured personnel were treated at the site and the US Air Force transport plane was damaged, police said in a report.
US military officials did not immediately respond to an Associated Press request for more details about the incident, including the condition of the injured personnel.
The training, involving the plane landing on and taking off from an “alternate landing zone,” was planned and fully coordinated with Philippine civilian, police and military authorities, three Philippine officials said. The training was meant to prepare military forces for contingencies, such as when regular airports and runways become inaccessible during typhoons and earthquakes.
The three officials, who spoke to the AP on condition of anonymity because they were not authorized to discuss the accident publicly, said the cause of the accident was under investigation. The aircraft managed to land during the “supervised activity,” but swerved during takeoff, one of the three officials said.
The US military had deployed aircraft and personnel in the past to help deliver food, medicine and other humanitarian aid to Philippine provinces devastated by typhoons and other natural disasters.
US forces are allowed to conduct training with Filipino counterparts in the Philippines under a 1999 Visiting Forces Agreement. Large-scale joint combat training drills in recent years have focused on helping the Philippines defend its territorial interests and promote freedom of navigation and overflight in the South China Sea, which lies west of Pangasinan.
Confrontations between the coast guard and naval forces of China and the Philippines have flared in recent years in the disputed waters, which is claimed largely by Beijing. Vietnam, Malaysia, Brunei and Taiwan are also involved in the long-simmering territorial standoffs.
The US does not lay any claims in the contested waters but has repeatedly warned that it’s obligated to defend the Philippines under a mutual defense treaty if Philippine forces, ships and aircraft come under an armed attack, including in the South China Sea.
