Richard J. and Eleonore D. Morgner, the Vienna couple killed in the Aug. 13 private plane crash in Mount Pocono, Pa., had lived in the Washington area since coming to this country in 1954 from their native Germany.

Mr. Morgner, 72, who had attended George Washington University, worked as a structural engineer in Washington before co-founding Superior Iron Works Inc. in Sterling, in 1968. He retired in 1992.

Mrs. Morgner, 76, a homemaker, had belonged, with her husband, to the Rolls Royce Owners Club, the Fairfax Country Club and the Aircraft Owners and Pilots Association.

An Aug. 15 story in The Washington Post reported that the Morgners had taken off from Manassas Regional Airport in their single-engine Cessna plane on Aug. 13 and were bound for Pocono Mountains Municipal Airport in Mount Pocono.

Authorities said that the pilot, Mr. Morgner, had more than 30 year's flying experience and that the airport was surrounded by a thick early morning fog when he tried to land. Residents near the airport reportedly heard the plane circling the airport before the crash. An official also reported that the plane disintegrated on impact.

Their survivors include two children, Andreas B. Morgner of Vienna, and Evelyn Morgner-Hogg of London; and five grandchildren. Mr. Morgner also is survived by two sisters; and Mrs. Morgner by two brothers; and a sister.
