When Jack Graham’s mother was killed in a plane crash, nobody knew what had caused the tragedy. Then investigators noticed something strange.
Early one November evening, United Airlines Flight 629 takes off from a Colorado airport with 44 people on board. Just 11 minutes into the flight, the airplane bursts into flames, sending burning debris tumbling to the ground below. But when investigators take a closer look, they discover something suspicious in a victim’s purse.
At 6:11 p.m. on November 1, 1955, Flight 629 landed at Stapleton International Airport, the main airfield in Denver, CO. Having begun its journey at La Guardia Airport in New York City, the aircraft had stopped in Chicago, Illinois, before arriving in Denver.
