Boeing 7J7
The Boeing 7J7 was an American short- to medium-range airliner proposed by American aircraft manufacturer Boeing in the 1980s. It would have carried 150 passengers and was touted as the successor to the successful Boeing 727. It was initially planned to enter service in 1992. This was intended as a highly fuel-efficient aircraft employing new technologies, but it was postponed indefinitely as the price of oil dropped during the 1980s. Development The 7J7 was the culmination of Boeing's Seven Dash Seven (7–7) 150-seat aircraft idea, which the company had considered since at least 1981. It was to be Boeing's second attempt at a replacement for the Boeing 727, its successful but aging 150-seat aircraft. The Boeing 757, a larger airplane that Boeing expected existing 727 customers to upgrade to, had unexpectedly slow sales leading to its 1983 entry into commercial service, as airline deregulation resulted in airlines using smaller aircraft at increased frequencies.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Saab-Scania
Saab-Scania AB was a Swedish vehicle manufacturer that was formed from the 1969 merger of Saab AB and Scania-Vabis. The company was split in 1995. History Truck and bus manufacturer Scania AB of Södertälje merged with car and aeroplane manufacturer Saab AB of Trollhättan on 1 September 1969, under the Wallenberg family group of companies. The merger meant that Saab no longer had to import the British Triumph Slant-4 engine, and could instead use the engine production facilities of Scania. In 1972 they started manufacturing the 2.0 L B version. In 1977, Saab took advantage of Scania's experience with turbochargers and added one to the engine, thus creating one of the earliest turbocharged automobile engines to be produced in large numbers. When the corporation was split in 1995, the name of the truck and bus division changed back to Scania AB. Saab Aircraft (Saab AB) and Saab cars were also split, with General Motors buying a major holding in Saab Automobile AB. Divisio ...

578-DX
The Pratt & Whitney/Allison 578-DX was an experimental aircraft engine, a hybrid between a turbofan and a turboprop known as a propfan. The engine was designed in the 1980s to power proposed propfan aircraft such as the Boeing 7J7 and the MD-91 and MD-92 derivatives of the McDonnell Douglas MD-80. As of 2019, it is still one of only four different contra-rotating propfan engines to have flown in service or in flight testing.
