Four Lockheed C-141B Starlifters were night air refueling/airdrop training mission. A KC-135 tanker was leading the Starlifters in a refueling pattern at FL255. The first Starlifter completed refueling and backed away to the left behind the KC-135 at FL250. It remained at an unusually close position. When the second C-141 had completed refueling it also backed away to the left, unaware of the unusual position of the first C-141. Both aircraft collided, breaking up in mid-air.
