A C-17 cargo aircraft piloted by Hickam Air Force Base commander Col. William J. Changose collided with a Hawai’i Air National Guard tanker aircraft about 200 miles off O’ahu during refueling training Thursday, officials said.
The collision sent the Air Guard KC-135R into a dive, causing some tense moments for its crew in the zero-gravity drop, but both planes landed safely.
No official word on whether there was body-to-body contact, or if it was just boom contact. There were over 100 people aboard the C-17, which was conducting training in anticipation of the arrival of eight C-17s in Hawaii next February.
