List of missing aircraft
This list of missing aircraft includes aircraft that have disappeared and whose locations are unknown. According to Annex 13 of the International Civil Aviation Organization, an aircraft is considered to be missing "when the official search has been terminated and the wreckage has not been located". However, there still remains a "grey area" on how much wreckage needs to be found for a plane to be declared "recovered". This list does not include every aviator, or even every air passenger that has ever gone missing as these are separate categories.
In the tables below, each missing aircraft is defined using one or more identifying features. If the aircraft was known by a custom or personalized name, that name is presented first followed by the aircraft type. The make of aircraft, although not necessarily a unique identifier, is also provided where appropriate. Aircraft registrations began to be used in the early 20th century for individual identification, so this is also included in the later tables.
