Antique, classic, heritage, historic, veteran or vintage aircraft are aircraft of an obsolete type which have been preserved beyond their normal life. Their owners are typically aviation museums, armed forces or private enthusiasts. Sometimes they may be maintained in an airworthy condition so that they can be flown at air displays or on public occasions. For example, the Battle of Britain Memorial Flight consists of RAF aircraft from WW2 and took part in a flypast at the wedding of Prince William and Catherine Middleton in 2011 — over 65 years after they were constructed.
Organisations devoted to such aircraft include the Antique Airplane Association, the Historic Aircraft Association and the Vintage Aircraft Association.
