FateOn display

The "City of Everett", is a Boeing 747, registered as N7470, that was built by Boeing as the prototype of the type. The aircraft rolled off the assembly line on September 30, 1968, and had its first flight on February 9, 1969. After the conclusion of the 747-flight testing program, Boeing retained the aircraft, using it for research and testing purposes until the early 1990s. The aircraft took its final flight on April 6, 1995, to the Museum of Flight in Seattle, Washington where it remains on display.

Birth of the Jumbo Jet

On September 30, 1968, the Boeing 747-100 prototype, registered as N7470 had rolled off the production line at the Boeing Everett Factory, a massive building that was constructed to build the 747 and was built almost simultaneously with the aircraft. [2] [3] The aircraft carried manufacturer serial number 20235 [3] and was designated internally as RA001,[ clarification needed ] marking the beginning of the era of the "jumbo jet". [4]

N7470 has a paint design featuring a simple white and red livery adorned with the logos of the more than two dozen airline customers who had ordered the aircraft type. [5]

Given its origin from the Everett production factory, Boeing nicknamed the aircraft the "City of Everett." [6]

Certification flights

Although N7470 was publicly revealed in September 1968, it didn't take to the skies until February 9, 1969. [3] The inaugural flight was piloted by Boeing Chief Test Pilot Jack Wadell, accompanied by Engineering Test Pilot Brien Singleton Wygle and Flight Engineer Jesse Arthur Wallick. This historic test flight marked the beginning of the Boeing 747's journey. [7] N7470 continued its test flying duties until the type was certified by the Federal Aviation Administration (FAA) on December 30, 1969. [8]

Use as Boeing testbed

After the 747 test flights, Boeing re-registered the aircraft as N1352B in July 1970 to explore missions beyond its original design specifications. These missions were primarily military, including using N1352B as a refuelling tanker for the Lockheed SR-71 Blackbird and the Boeing B-52 Stratofortress. Unfortunately, the idea of using the Boeing 747 as a refuelling tanker wasn't ideal, and the aircraft was eventually re-registered back to its original identity as N7470.[ citation needed ]

The plane was stored in Las Vegas between October 1983 and August 1986, when it was sent to Wichita where it was used as a mockup for the development of the Boeing VC-25, the aircraft commonly associated with Air Force One. [8]

The aircraft also served as a testbed for the Pratt & Whitney PW4000 turbofan during its development for the Boeing 777. [3]

Boeing retained ownership of N7470 over its entire lifetime in service, never being delivered to a customer and never being used in commercial service. [9] The aircraft only accumulated about 5,200 hours of flight time over its lifetime, relatively low compared to a commercial aircraft which typically sees 3,000 to 4,000 hours every year. However, the aircraft was subjected to more extreme conditions including repeated stalls and dives. [8]

Retirement and preservation

On April 6, 1995, N7470 embarked on its last-ever flight. [8] The aircraft, still in its test-configured state, was donated to the Museum of Flight located at Boeing Field in Seattle, Washington where it was placed on static display.

By the early 2000s, the aircraft was in need of restoration due to its advanced age and prolonged exposure to the wet weather of the Pacific Northwest. [10]

The board of the Museum of Flight authorized the restoration in the summer of 2012 and embarked on a nearly two-year-long effort. The aircraft was restored in place, not moved into a hangar, which complicated the effort. On the aircraft's exterior, the faded paint was sanded down, and crews applied more than 60 gallons of fresh paint. The interior, damaged with mildew, was restored to the aircraft's first-flight configuration, with testing equipment on the main deck, and period-appropriate upholstery was located to recreate the upper deck lounge's furniture. The aircraft reopened for public tours in 2014. [11] [12] After the restoration, a large roof was built over the Museum's Aviation Pavillion to better protect N7470 and the other aircraft on display.

The Boeing 747 is a long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. After the introduction of the 707 in October 1958, Pan Am wanted a jet 2+1⁄2 times its size, to reduce its seat cost by 30%. In 1965, Joe Sutter left the 737 development program to design the 747. 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. On September 30, 1968, the first 747 was rolled out of the custom-built Everett Plant, the world's largest building by volume. The 747's first flight took place on February 9, 1969, and the 747 was certified in December of that year. It entered service with Pan Am on January 22, 1970. The 747 was the first airplane called a "Jumbo Jet" as the first wide-body airliner.

The Boeing KC-135 Stratotanker is an American military aerial refueling tanker aircraft that was developed from the Boeing 367-80 prototype, alongside the Boeing 707 airliner. It has a narrower fuselage and is shorter than the 707. Boeing gave the aircraft the internal designation of Model 717. The KC-135 was the United States Air Force (USAF)'s first jet-powered refueling tanker and replaced the KC-97 Stratofreighter. The KC-135 was initially tasked with refueling strategic bombers, but it was used extensively in the Vietnam War and later conflicts such as Operation Desert Storm to extend the range and endurance of US tactical fighters and bombers.

With versions produced until 1979, the 707 is a swept wing quadjet with podded engines. Its larger fuselage cross-section allowed six-abreast economy seating, retained in the later 720, 727, 737, and 757 models.

The Boeing 777, commonly referred to as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. The 777 is the world's largest twinjet and the most-built wide-body airliner. The jetliner was designed to bridge the gap between Boeing's other wide body airplanes, the twin-engined 767 and quad-engined 747, and to replace aging DC-10 and L-1011 trijets. Developed in consultation with eight major airlines, the 777 program was launched in October 1990, with an order from United Airlines. The prototype aircraft rolled out in April 1994, and first flew in June of that year. The 777 entered service with the launch operator United Airlines in June 1995. Longer-range variants were launched in 2000, and first delivered in 2004.
