Jack Gilbert Graham

Jack Gilbert Graham was a mass murderer who killed 44 people by planting a dynamite bomb on board a United Airlines Douglas DC-6 taking off from Denver, Colorado on November 1, 1955. Jack's mother was on board the plane - the motive for the bombing was to claim $37,500 worth of life insurance money, from policies bought in the airport just before take-off.

Jack Gilbert Graham was executed in the Colorado State Penitentiary gas chamber on January 11, 1957.

The Jack Gilbert Graham case may have been the inspiration for the 1970 movie Airport.
