As the aircraft was climbing through 19000ft, Auburn R. Calloway, a Federal Express employee who was deadheading on the flight, entered the galley, opened a guitar case he brought onboard, took out a mallet, and reentered the cockpit. He struck Captain David Sanders, First Officer James Tucker Jr., and Flight Engineer Andrew Peterson multiple times. Sanders and Tucker received fractured skulls, and shards of Tuckers skull hit his brain, temporarily paralysing him. Calloway returned to the galley to retrieve a spear gun. When he returned to the cockpit, Sanders and Peterson fought back, and as Tucker came to, he joined the fight, however he used the aircraft as his weapon. He pulled the plane into a sudden climb, throwing the three men out the cockpit door, then he entered a left roll, eventually reaching almost 140⁰ of bank, then, a steep dive. Despite this Calloway managed to lay some more blows on Sanders and Peterson, despite the two men losing strength, blood, and Peterson going into shock, they managed to grab the hammer off Calloway and strike back. Eventually Captain Sanders returned to the cockpit, and Tucker joined Peterson in subduing Calloway. The aircraft safely landed, Calloway was arrested, and Sanders, Tucker, and Peterson were taken to hospital. ALPA gave the pilots the Gold Medal Award, and Calloway is still in prison to this day. The aircraft, a DC-10-30, N306FE suffered severe structural damage, however it was repaired, and in 2008 upgraded to an MD-10. It was finally retired on December 31st 2022.
