Crash Victims Friends and relatives of Don and Edith Mercer said their final good-byes Saturday. The Hendersonville couple died Wednesday when their single-engine plane crashed near St. Louis.
Witnesses say the propeller came off the plane in-flight.
Friends said Don Mercer, who founded what is now Dynatech Incorporated, was dedicated to spreading the Christian gospel. He and his wife were on their way to a relative's funeral when their plane went down. A broken crankshaft has been mentioned as a possible cause for the crash.
