With a ten-abreast economy seating, it typically accommodates 366 passengers in three travel classes. The 747 is a four-engined jet aircraft, initially powered by Pratt & Whitney JT9D turbofan engines, then General Electric CF6 and Rolls-Royce RB211 engines for the original variants. The 747 was the first airplane called a "Jumbo Jet" as the first wide-body airliner. It entered service with Pan Am on January 22, 1970. The first flight took place on February 9, 1969, and the 747 was certified in December of that year. On September 30, 1968, the first 747 was rolled out of the custom-built Everett Plant, the world's largest building by volume. In April 1966, Pan Am ordered 25 Boeing 747-100 aircraft, and in late 1966, Pratt & Whitney agreed to develop the JT9D engine, a high-bypass turbofan. ![]() In 1965, Joe Sutter left the 737 development program to design the 747, the first twin-aisle airliner. NOTE: This applies to standard business hours, after hours you may find street-level doors on certain buildings locked, even if you can clearly see people still using the skyway.The Boeing 747 is a large, long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 19.Īfter introducing the 707 in October 1958, Pan Am wanted a jet 2 + 1⁄ 2 times its size, to reduce its seat cost by 30%. Helpfully, many elevators in downtown Minneapolis have a ‘SK’ button in place of a ‘2’. Just find your way to the second level of any skyway-connected building and you’ll find skyway access. All part of the adventure!Ī good rule of thumb for finding one’s way into the Skyway System from the street is if the building has a skyway connected to it, you can almost certainly find an access point. This effort improved navigation, and has evolved dramatically in helpfulness, but alas, people can still be seen standing in skyway junctions, heading spinning around, trying to figure out where to go next. With skyways now included in nearly all new construction in central downtown, maps and way finding signage became necessary. Bank Stadium to the rest of the system brought the total length of pathways to over 8 cumulative miles. The IDS junction also features the Crystal Court atrium, still the largest open public space in the network. The building featured skyways connecting to buildings in all four directions, which integrated what was up until then a scattered system. The construction of the IDS in 1974 (still the tallest building in downtown Minneapolis) was a key moment for the skyway network. ![]() Wandering the system, you’ll probably be able to identify the skyway routes that were plugged into existing buildings – sometimes awkwardly. It was immensely popular, so slowly but surely new skyways appeared, often, but not always in conjunction with new construction. The city's first skyway connecting the new Northstar Center building to the Northwestern Bank Building opened in 1962. ![]()
