A talk-down landing may be attempted in the event of the death or incapacitation of an aircraft pilot. It involves a passenger or other unqualified person flying the aircraft to a landing with assistance from radioed instructions either from the ground or a nearby aircraft.
There is no record of a talk-down landing of a large commercial aircraft. There have, however, been incidents where qualified pilots travelling as passengers or flight attendants on commercial flights have taken the co-pilot's seat to assist the pilot.[1]
