Not sure if this has been discussed before here. I just find the story incredible.
"FedEx Flight 705, a McDonnell Douglas DC-10-30, experienced an attempted hijacking for the purpose of a suicide attack on April 7, 1994 by a FedEx employee facing possible dismissal. The hijacker, as an employee, was able to board a scheduled flight with several concealed weapons. Once airborne he intended to kill the crew and then fly the DC-10 into FedEx headquarters. He believed that death while still an employee in addition to the choices of weapons, which were meant to conceal the hijacking, would make his family eligible for a $2.5 million life insurance policy paid by the company he was both employed by and targeted.
The hijacking was unsuccessful, as the crew was able to fight back, despite severe wounds, subdue the attacker, and safely land the aircraft."
You can watch the National Geographic documentary about the incident with commentary from the actual pilots.
The clip is the only ATC audio I could find.
