An interesting article on the history and current state of the 747 market:
For decades, the Boeing 747 was the Queen of the Skies. But the glamorous double-decker jumbo jet that revolutionized air travel and shrunk the globe could be nearing the end of the line.
Boeing has cut its production target twice in six months. Just 18 will be produced in each of the next two years. Some brand-new 747s go into storage as soon as they leave the plant. Counting cancellations, it hadn’t sold a single 747 this year until Korean Air bought five on Thursday.
Boeing says it’s committed to the 747, and sees a market for it in regions like Asia. But most airlines simply don’t want big, four-engine planes anymore. They prefer newer two-engine jets that fly the same distance while burning less fuel.
