On April 7, 1994, Federal Express Flight 705, a McDonnell Douglas DC-10-30 cargo jet carrying electronics equipment across the United States from Memphis, Tennessee, to San Jose, California, was involved in a hijack attempt by Auburn R. Calloway, who the prosecution argued was trying to commit suicide. Calloway, a Federal Express employee, was facing possible dismissal for lying about his flight hours. He boarded the scheduled flight as a deadhead passenger carrying a guitar case concealing several hammers and a speargun. He tried to switch off the aircraft's cockpit voice recorder (CVR) before takeoff and, once airborne, kill the crew with hammers so their injuries would appear consistent with an accident rather than a hijacking. The CVR, though, was switched back on by the flight engineer, believing that he had neglected to turn it on.Calloway intended to use the speargun as a last resort. He planned to crash the aircraft hoping that he would appear to be an employee killed in an accident. He sought to let his family collect on a $2.5 million life insurance policy provided by Federal Express. Calloway's efforts to kill the crew were unsuccessful. Despite severe injuries, the crew fought back, subdued Calloway, and landed the aircraft safely.

During his trial, Calloway attempted to invoke an insanity defense, but he was found guilty of multiple charges, including attempted murder, attempted air piracy, and interference with flight crew operations. He received two consecutive life sentences with no chance of parole. Calloway successfully appealed the conviction for interference, which was ruled to be a lesser offense of attempted air piracy.
