SEOUL, South Korea — Two South Korean air force planes collided in mid-air during training and crashed near their base on Friday, killing all four people aboard the aircraft, officials said.
Both planes were KT-1 trainer aircraft — South Korea's first indigenously developed planes — that took off from an air force base in the southeastern city of Sacheon one after another for flight training, the air force said in a statement.
The collision occurred about five minutes after the first aircraft took off and about 6 kilometers (3.7 miles) south of the Sacheon base, the air force said.
Two people — a trainer pilot and an instructor — were aboard each of the two KT-1 aircraft. All four ejected from the planes but were later found dead, the air force statement said. The four victims were identified as two first lieutenants and their instructors, both civilian employees at the air force.
The air force said it will launch a task force to investigate what caused the collision.
The air force said the crashes didn't cause any civilian casualties on the ground and it was trying to determine if any civilian property was damaged.
Lee Seong-gyeong, a Sacheon police official, said a passenger car was destroyed after being hit by wreckage but added that officials weren't immediately aware of any other notable damage to civilian property. South Korean media published photos of the mangled vehicle surrounded by scattered machinery…
