On the hard-packed sands of California’s Mojave Desert stands a surreal sight. Hundreds of decommissioned commercial jets are lined up row after row, in the middle of nowhere. Their engines are taped shut with Mylar to keep out drifting sands. This is a graveyard for retired jets, many of which originally cost hundreds of millions of dollars to build. Now they only serve as awnings for rattle snakes and reptiles that take shelter from the unrelenting sun. Some planes may be stripped of useful parts that can be reconditioned. Others may be bought by a third-world country or short-hop commuter startup. And still others will simply languish there for years – a kind of “Stonehenge” of the 21st century.
