The Southern California Logistics Airport in Victorville, California, USA contains an aircraft boneyard with more than 150 retired planes. Because the demand for jumbo jets has dropped significantly in the last two decades in favor of smaller, more affordable twin-engine planes, many large aircrafts such as Boeing 747s have been retired. The dry conditions in Victorville – located on the edge of the Mojave Desert – limits the corrosion of metal, meaning planes can be stored here for years while they are stripped for spare parts.
