THE BOEING 720

摘要

The four-engine 707-Boeing's long-haul masterpiece-entered service in 1958. With the market for jet transports linking major cities of the world sewn up, Boeing shifted its attention to the next market segment; short- and medium- haul flights between smaller cities. By shrinking the 707, they added a new type to their product line-the new Boeing 720-which became the first jet to serve many of the airports it connected and the first turbine-powered aircraft for seven of the 16 customers that bought it.
