Checkout these incredible photos from where jumbo jets go to die

The days of the jumbo jet are numbered. Since their debut in the late 1960s, Boeing 747 and McDonnell Douglas DC-10 have been the undisputed queens of the sky.

Unfortunately, the size, four-engine dependability, and range of these big planes are no longer enough of a competitive advantage to justify their operating costs. These relics of the 20th century often end up in places such as the Southern California Logistics Airport — more commonly known as the “bone yard.”

The Southern California Logistics Airport is located in Victorville, California -- about 80 miles northeast of Los Angeles.

Due to its location in the Mojave desert, Victorville's warm and dry climate make it the perfect place to keep ageing aeroplanes for extended periods of time.

Aeroplanes here have either been retired or declared 'surplus' -- not needed for immediate operations.

After they arrive, some planes are preserved so they can, one day, return to service with the airline or ...

... be sold to another airline.

Those planes have their windows covered in foil and their fluids drained as they prepare for to sit in the desert for the long haul.

The aircraft's engines -- the most valuable parts of the plane - are also removed.

Old aeroplanes, including Boeing 747-400s, are stored in the desert in Victorville, California March 13, 2015.

However, others -- like this ex-Orient Thai Boeing 747 -- are broken up and sold for parts.

After the valuable parts, such as the electronics, interior trim, and other reusable components have been harvested, the remaining pieces are chopped up and sold for scrap.

As of March 2015, British Airways has quite a few 747s at the bone yard.

The airline has a massive fleet of more than 50 747-400s.

But as the average age of their 747 fleet near 20 years, British Airways is slowly retiring its older birds.

In addition to BA, Singapore Airlines, Air New Zealand, and Cathay Pacific have sent their 747s to Victorville.

Other airlines include, Air China, Evergreen International, Lufthansa, and United Airlines.

FedEx is also a major tenant.

The cargo carrier is in the process of updating its massive fleet of mostly older jets.

As a result, many of its older McDonnell Douglas DC/MD-10, and MD-11 freighters have been retired to the desert.

FedEx has also retired some of its Airbus A300 and A310 freighters.

There are some smaller jets here, as well. Like this trio of retired FedEx Boeing 727 cargo planes.

Here, a trio of ex-Aeroflot MD-11F cargo jets sits next to 3 ex-United Airlines Boeing 757-200s.

Mixed in with the FedEx jets are some ex-Delta Airlines Boeing 767s.

The bone yard is an ever-changing aviation landscape. As old tenants of broken up or sold, new arrivals fresh from mainline service are flown in.

As airlines retire their 747s, one wealthy individual bought a new jumbo to be his private jet...
