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."
