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.
