>>Hoverman - you perhaps never heard about Fedex flight engineer who attacked crew with a hammer while taking jumpseat ride. Heard his plan was to fly into fedex HQ to pay them back for sacking him. Not sure about all the details.<<
That was the infamous case of Auburn Calloway. Of course, Auburn claimed that he was a victim of "racial profiling" and that the crew actually attacked him in a racist assault. He also complained that he was not properly evacutated from the aircraft - he was tossed down the slide after trying to kill the crew rather than being carried down on a stretcher. He apparently intended to crash the DC-10 into the FedEx afternoon sort in MEM. He had the usual suicide note, recent insurance policy etc.
Here's one of many accounts of the incident that may be found online:
"The FAA document and news reports on the incident paint the following picture if this April 7, 1994 event. Auburn Calloway, an off duty Federal Express second officer, was riding in a courier seat outside the cockpit of a Federal Express DC-10. Calloway was the lone passenger on this Memphis to San Jose flight. Shortly after takeoff, Calloway entered the flight deck and attacked the crew with a pair of hammers. During the ensuing bloody struggle, the first officer and flight engineer were able to force Calloway out of the cockpit while the captain put the aircraft through a series of extreme dives and turns in an effort to knock Calloway off balance. For a short time, the aircraft was on autopilot as the crew attempted to get Calloway out of the cockpit. The captain was able to return the aircraft safely to Memphis while the other two crew members continued the struggle all the way to the ground. All of the occupants were injured, and only the captain escaped serious injury.
The attack was apparently planned. Calloway also had other weapons - a spear gun, a hunting knife, and two other hammers - on the aircraft. There was also a note that indicated that Calloway intended to commit suicide. Calloway's attack also occurred one day before a scheduled personnel hearing with his superiors, reportedly concerning allegations of false information on his job application. Calloway is currently a long term resident of a federal corrections facility. "
