On this date in 1962, Continental Airlines Flight 11, enroute from Chicago to Kansas City, MO, crashed in Unionville, MO, killing all 45 of the Boeing 707′s occupants.
Several eyewitness accounts described an explosion at the rear of the plane while it was over Centerville, IA. Once it became apparent that an explosive device might be involved, the FBI was called in. They discovered that one of the passengers had purchased an inordinate amount of life insurance just prior to the flight. In addition to insurance, Thomas G. Doty also purchased six sticks of dynamite before his trip. The married father of a five year old daughter was facing prison time for an armed robbery.
Investigators believed that the bomb had been hidden in the rear lavatory on the starboard side of the plane. The explosion tore the tail section off the 707, which caused it to crash.
In July 2010, a memorial was erected in Unionville, MO.
