Continental Airlines Flight 11, registration N70775, was a Boeing 707 aircraft which exploded close to Centerville, Iowa, while en route from O'Hare Airport, Chicago, Illinois, to Kansas City, Missouri, on May 22, 1962. The aircraft crashed in a clover field near Unionville, in Putnam County, Missouri, killing all 45 crew and passengers on board. Flight 11 departed O'Hare at 8:35 PM. The flight was routine until just before the Mississippi River, when it deviated from its filed flight plan to the north to avoid a line of thunderstorms. In the vicinity of Centerville, Iowa, the radar image of the aircraft disappeared from the scope of the Waverly, Iowa, Flight Following Service. At approximately 9:17 p.m. an explosion occurred in the right rear lavatory, resulting in separation of the tail section from the fuselage. The aircraft broke up and the main part of the fuselage struck the ground about 6 miles north-northwest of Unionville, Missouri. Witnesses in and around Cincinnati, Iowa, and Unionville reported hearing loud and unusual noises at around 9:20 p.m., and two more saw a big flash or ball of fire in the sky.
