Lake Central Airlines Flight 527
[1] On March 5, 1967, Lake Central Airlines Flight 527 was scheduled from Chicago, Illinois to Detroit, Michigan.The flight, operated by one of the company's Convair 580 aircraft and flown by captain John W. Horn (45) and first officer Roger P. Skillman (33), left Chicago at 4:04 p.m. CST and proceeded normally to Lafayette, Cincinnati and Columbus.[1] The aircraft was equipped with a flight data recorder, which sustained no damage in the crash and was successfully read by investigators.[1] The cockpit voice recorder lost power at the same time, although investigators heard a sound resembling "the first few seconds of an air raid siren" just before shutoff.When the propeller failed, the blades were hurled through the cabin, severing control cables and compromising the plane's structural integrity.
