.. make the plane six seats abreast. Douglas was the main competition in the beginning has a plane that was five seats abreast. Even with Douglass advantage in speed and range it could never match the seat per-mile cost the 737 gave. The single decision, which meant about a 17inch increase of diameter over the DOUGLAS DC-9, meant the success of the 737 and the failure of the DC-9.
Above: Comparison between the DC-9 and 737 cross-sections. With the ruggedness of the 737 it sees several applications for the Military. Its most widely used application is as a training aid for both pilots and navigators. Pilots use the USAF designated T-43 737s as a flight trainer for large cargo and transport aircraft. The 737 is a large aircraft but not too large aircraft, it provides the perfect stepping stone for pilots into the huge birds that are present in todays Air Force.
It also provides navigational training. Its wider design offers plenty of room for the trainees and their instructors. One T-43 has about 19 stations for its students (Minton, 31). The T-43 provides a very accommodating learning environment for the flight students. The largest and most infamous member of the family is the Boeing 747, the Jumbo Jet.
This is an aircraft that has changed commercial airliners forever. With its sheer size it put itself in a class of its own. The 747 offer a lower seat per-mile cost and a more efficient way for transportation than any other aircraft. It can move more people and cargo farther and faster. The 707 brought jet transportation to people. The 747 brought jet transportation to the everyday people (Norris and Wagner, 26).
747s have become the backbone of many airlines, in that they handle more people and cargo than any of their other planes. 747 not only provides a highly efficient people mover it has also been a great improvement of cargo transportation. Some modified 747 have a large upward swinging door at the nose of the plane. This door allows for great ease in loading large cargo items. Boeing also offered the option of a side panel door for loading. This was mainly used in the Combi 747; they were 747 they would transport people and cargo at the same time.
The 747 also serve several roles in the Military. Most notably is in the application of presidential transportation as Air Force One. The 747 replace the 707 as Air Force One with great pride. With the increase in room and luxury the President hasnt had a better ride since. The 747 also found itself the solution to a rather large problem that is of the transportation of the Space Shuttle. There really is no other way to transport the large orbiter than strapping it onto the top of a 747.
NASA bought an ex-American Airlines 747 in 1977 and has been using it ever since (Gilchrist, 61). By the late seventies the 727 and 737 were showing their age. Boeing was unable to sell newly modified versions of the two aircraft and they soon realized that a whole new aircraft was in need. The new aircraft did not come in the form of a single plane but in two completely different airplanes that would pick up the slack in the short to medium range jet planes. These planes would be the 757 and the 767.
They would prove to be very qualified successors to the 727 and the 737 proving themselves in both the commercial and military world. In fact the 767 came out of production with great performance than what was original planned. Getting it into service, getting it under our original cost estimates and one day early-I dont know how you can improve on that. And thats due to the great team at Boeing (Bauer, 320). The short to medium range jet had been modernized with increases in performance of its capacity, speed, and fuel consumption.
The Military had their eye on the 767. It was as wide-bodied aircraft similar in dimensions to the 737 and the wider body is what the Military saw most appealing. One of the primary functions the 767 serves is in the AWACS (Airborne Warning and Control System) program. It is a 767 modified with a large circular disc on the top. The disc is composed of radars and antennas, it purpose is to target and track targets from a long range, this information is then communicated to fighters on stand by.
The body of the plane has a crew and a large amount of computer equipment used in the process of determining targets. Boeing has some more plans for the 767, Boeing see it a very capable candidate for a tanker/transport variant that would provide in flight refueling and transportation duties (www.Boeing.com). The last in the family is the 777, which were introduced, in the early nineties. It is a complete new generation of aircraft with the complete integration of computers. The 777 has two main variants presently they are the 777-200 and the 777-300.
Their main difference is length and capacity, the 300 is about 33 feet longer and can hold about 70 more passengers than the 200. Both will work to satisfy the different needs of an airline. A newer version is in the works too. It is the 777-400 planned to have even greater capacity that what is now present. The 777 should gradually replace the 747 as the large capacity long-range jet (www.Boeing.com).
The 777 are the plane of the future and will have many service roles in the commercial world. The line of the Boeing 700 aircraft is undeniably a very versatile line of aircraft. From the beginning they have dominated in commercial jet sales and for good reason. Boeing has always made their aircraft with the utmost quality and attention to detail. Boeing will test and test again until they get it right and that shows in their products.
The 700s serve any commercial and military need placed on them. They have made long distant travel a comfort and a pleasure to many. It is hard to imagine what is would be like without Boeing. It is very safe to say that commercial airline travel would simply not be at the same caliber we find it today.
