On 1 November 1955 , six years after the bombing , a later copycat airplane bombing was apparently inspired by the Guay affair . The bombing of United Airlines Flight 629 by Jack Gilbert Graham killed 44 people , all aboard the flight including his mother . Graham 's reported motive was his mother 's alleged mistreatment of him as a small child , but featured similarities to Guay 's bombing including placing a dynamite time-bomb in the target 's suitcase , and collecting life insurance on them shortly before the flight departure
