Boeing 747 Boeing
747
Long-Range Jetliner

DESCRIPTION:
When the US Air Force requested proposals for a heavy cargo transport, Boeing submitted a design that would eventually become the 747. As with the 707 and KC-135, it was hoped that government funding for a military project would reduce the cost of developing a commercial derivative for the airline market. However, Lockheed won the Air Force contract and went on to build the C-5 Galaxy. Despite development costs exceeding $16 million, Boeing decided at great risk to the survival of the company to proceed with the commercial 747 with internal resources once airlines had shown enough interest in the design.

Boeing even went so far as to build an entirely new factory for 747 production because the aircraft was so much larger than its predecessors. The fuselage is enormous, with a main deck seating nine abreast plus an upper deck lounge aft of the flight deck. To operate such a heavy aircraft from existing runways, the weight had to be dispersed over 18 wheels on five landing gear units. Despite its bulk, the 747 was designed to be as similar to smaller Boeing designs, like the 707 and 727, as possible to ease crew familiarization and airport compatibility. The 747 uses powered controls and advanced navigation systems so that early models required only three flight crew to operate the aircraft. The current 747-400 production models employ further advanced automation technologies to reduce the flight crew to two.

Although the 747 typically carries 300 to 500 passengers, this represents only a fraction of the aircraft's lifting capability. High-density versions flown in east Asia routinely carry up to 800, and one Israeli 747 airlifted a staggering 1,087 refugees from Ethiopia in 1991.

By 2001, over 1,250 747s had been built. Further development of the series continues with the 747-400ER extended range and 747-8 stretched models, although development problems with the 787 have delayed the 747-8 series by about two years. Boeing hopes these improvements will keep the 747 line competitive with the Airbus A380. Long term plans are for an entirely new large, long-range airliner to be developed around 2020 as a replacement for both the 747 and 777.
