747 wingspan1/12/2024 ![]() It incorporates the strengthened -400 Freighter wing, strengthened body and landing gear, and an auxiliary fuel tank in the forward cargo hold, with an option for a second tank. The airplanes are the same size as current 747-400s and have a range of 7,670 nautical miles (14,205 kilometers) as opposed to the 747-400 range of 7,260 nautical miles (13,450 kilometers). The 747-400ER (Extended Range) family is available in both passenger and freighter versions. The longer range 747-400 airplanes (also known as 747-400ERs) were launched in late 2000. The fourth and final Dreamlifter entered service Feb. The massive cargo is loaded and unloaded from a hinged rear fuselage. ![]() ![]() Air Force “bone yard” near Pima, Ariz., to be scrapped.Īnother variant is the Dreamlifter - a specially modified 747-400 - that transports the large composite structures, including huge fuselage sections of the 787 Dreamliner, from partners around the world to Everett, Wash., and Charleston, S.C., for final assembly. The program was canceled in 2011, and in 2012, YAL-1 was flown to the U.S. 11, 2010, the flying test bed destroyed a ballistic missile off the coast of Southern California. ABL partners were Northrop Grumman, which supplied the chemical oxygen iodine, or COIL, high-energy laser associated lasers, and Lockheed Martin, which provided the nose-mounted turret in addition to the beam control/fire control system. Boeing provided the modified aircraft and the battle management system and is the overall systems integrator. Boeing was the prime contractor for ABL, which was designed to provide a speed-of-light capability to destroy all classes of ballistic missiles in their boost phase of flight. 27, 2006, and was eventually designated YAL-1. Air Force’s Airborne Laser (ABL) program. In August 1999, major assembly began on a militarized 747-400 Freighter to be used as a platform for the U.S. The 747-400 also is produced as a freighter, as a combination freighter and passenger model, and as a special domestic version, without the winglets, for shorter range flights. Its wingspan is 212 feet (64 meters), and it has 6-foot-high (1.8-meter-high) "winglets" on the wingtips. The 747-300 has an extended upper deck and carries even more passengers than the -200. In 1990, two 747-200Bs were modified to serve as Air Force One and replaced the VC-137s (707s) that served as the presidential airplane for nearly 30 years. The next version, the 747-200, holds approximately 440 passengers and has a range of about 5,600 nautical miles (10,371 kilometers). The National Aeronautics and Space Administration later modified two 747-100s into Shuttle Carrier Aircraft. ![]() The pilot learned how to maneuver from such a height by directing the truck driver below him by radio. The pilot sat in a mockup of the 747 flight deck built atop three-story-high stilts on a moving truck. The experience of taxiing such a large plane was acquired in a contraption called "Waddell's Wagon," named after Jack Waddell, the company's chief test pilot. Pilots prepared for the 747 at Boeing training school. Yet, the entire global navigation system weighed less than a modern laptop computer. The total wing area was larger than a basketball court. The cargo hold had room for 3,400 pieces of baggage and could be unloaded in seven minutes. The fuselage of the original 747 was 225 feet (68.5 meters) long the tail as tall as a six-story building. The massive airplane required construction of the 200 million-cubic-foot (5.6 million-cubic-meter) 747 assembly plant in Everett, Wash., the world's largest building (by volume). The freighter and convertible models loaded 8- by 8-foot (2.4- by 2.4-meter) cargo containers through the huge hinged nose. The 747's final design was offered in three configurations: all passenger, all cargo and a convertible passenger/freighter model. The design philosophy behind the 747 was to develop a completely new plane, and other than the engines, the designers purposefully avoided using any hardware developed for the C-5. Following the loss of the competition for a gigantic military transport, the C-5A, Boeing set out to develop a large advanced commercial airplane to take advantage of the high-bypass engine technology developed for the C-5A. The incentive for creating the giant 747 came from reductions in airfares, a surge in air-passenger traffic and increasingly crowded skies. Called "the Incredibles," these were the construction workers, mechanics, engineers, secretaries and administrators who made aviation history by building the 747 - the largest civilian airplane in the world - in roughly 16 months during the late 1960s. The 747 was the result of the work of some 50,000 Boeing people.
