United Airlines Flight 629 Explodes
At 6:52 p.m. on November 1, 1955 United Air Lines Flight 629, a DC-6B with forty-four persons aboard, took off from Stapleton Airport, Denver, Colorado, bound for Portland, Oregon.
Eleven minutes later, the thirty-nine 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.
The four-engine prop DC-6B revved up its mighty turbines at the end of the runway with a tremendous roar. As the pilot released the wheel brakes, United Airlines flight 629 rolled down the narrow, bumpy tarmac gathering speed. The front wheel gently lifted from the ground as the nose of the aircraft pointed toward the heavens. Within moments, the sturdy airplane soared into the crystal blue sky and banked gracefully to the west, on its way to a 1,029-mile journey to Portland, Oregon. On board, Captain Lee Hall, an accomplished pilot and veteran of World War II, pulled steadily back on the control arm and within minutes, leveled off the plane at 4,000 feet. Visibility was good, and the crew, consisting of pilot, a co-pilot and three stewardesses, prepared for a leisurely flight over Colorado, Wyoming and Idaho.
