Airplane "boneyards" in the U.S. and in Europe serve several functions: temporary storage, maintenance, parts reclamation, and scrapping.
Commercial airliners and military aircraft have limited lifespans.
Some are temporarily removed from flying status, and must be stored in an environment that is conducive to preservation. Others are kept as spare parts for flying aircraft.
Eventually, as airframes wear out and economics change, aircraft are removed permanently from service and scrapped at an "airplane boneyard".
This video showcases some of the larger boneyards in the United States, Europe and Australia. It features some easy listening music, so turn up your volume and enjoy this tour of the largest airplane boneyards in the world!
Like all YouTube videos, you can mute the music, and also play full-screen if you desire.
