Jack Gilbert Graham - United Flight 629

At 6:52 p.m. on November 1, 1955 United Air Lines Flight 629, a
DC-6B with 44 persons aboard, took off from Stapleton Airport in
Denver, Colorado bound for Portland, Oregon. Eleven minutes
later, the 39 passengers, including an infant and five crew
members, were dead - killed instantly when the luxurious airliner
crashed on a sugar beet farm near Longmont, Colorado. But this
was not an act of terrorism, this was an angry son put together a
time bomb that was composed of 25 sticks of dynamite, two primer
caps, a timer and a six-volt battery into his own mothers'
suitcase.
