"About twenty minutes after takeoff, as the flight crew carried on a casual conversation, Calloway entered the flight deck and commenced his attack. Every member of the crew took multiple hammer blows which fractured [the flight crew's] skulls. A lengthy struggle ensued with the flight engineer and captain as Tucker, also an ex-Navy pilot, performed extreme aerial maneuvers with the aircraft, at times flying upside down, with the intent to keep the hijacker off-balance."

It worked, too. Everyone survived.
