SEOUL, South Korea (AP) — Two South Korean air force planes have collided in mid-air during training and crashed near their base, killing all four people aboard the aircraft. The air force said both planes were KT-1 trainer aircraft that took off from an air force base in the southeastern city of Sacheon one after another on Friday. It says 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 the plane crashes didn’t cause any civilian casualties on the ground. The cause of the collision is unknown.
