Jack Gilbert Graham was a disturbed young man, something that he blamed on his mother.
In fact, he was so disturbed, and blamed her so much, that in 1955, he made a bomb from dynamite and hid it in her luggage. His mother flew out of Denver that night, bound for Alaska to visit Jack’s sister.
The bomb blew up shortly after take off. The plan was destroyed, and not one of the 44 passengers and crew survived. Graham was arrested, tried and convicted. He was executed in the gas chamber on January 11, 1957.
