757 Commercial Transport

757 commercial transportThe twin-engine, medium-range 757 is up to 80 percent more fuel efficient than the older 727 jetliners it was designed to replace, but retained the 727's short-field capability. The 757-200 carried up to 228 passengers and had a range of approximately 3,900 nautical miles.

The 757 and the 767 were developed concurrently, so both shared the same technological advances in propulsion, aerodynamics, avionics and materials. The pioneering two-crew computerized flight decks or "glass cockpits" of the 757 and 767 are nearly identical, so pilots could easily qualify to fly both.

The first 757 rolled out of the Renton, Wash., factory in 1982. On March 29, 1991, a 757, powered by only one of its engines, took off, circled and landed at the 11,621-foot-high Gongga Airport in Tibet. The airplane performed perfectly although the airfield was in a box canyon surrounded by peaks more than 16,400 feet high.

In 1996, the company launched the 757-300. It seated up to 280 passengers and had about 10 percent lower seat-mile operating costs than the -200. The first 757-300 was delivered in 1999.

By then Boeing had delivered more than 1,000 757s. Four 757s were modified as replacements for the older 707-based VC-137 executive transports for government officials and designated C-32As.

On Nov. 28, 2005, Boeing concluded the remarkable 23-year run of the 757 passenger airplane by delivering the final one to Shanghai Airlines. The airplane was the 1,050th Boeing 757. The 757 is one of seven commercial models that have sold more than 1,000 airplanes, and more than 1,030 of the 757s were still in service during 2007.
