With plenty of value left in most aircraft after retirements, these ‘graveyards’ are not merely locations where the aircraft are left to decay. Some will be carefully stored and lightly maintained, pending a future return to service. Others may be similarly stored while a buyer is found at the right price. They may be kept for a long time for spare parts, as the price and need for these can vary significantly over time. Or they may simply be scrapped, with parts salvaged and sold as quickly as possible.
