Although originally conceived as a twinjet, the DC-10 gained a third engine at the base of its vertical tail to meet an American Airlines requirement that the aircraft be capable of operating from existing runways. The DC-10 subsequently was launched in February 1968 with orders from American and United. First flight took place on August 29 1970.

Nov 6, 2002 · The twin-engined DC-10 was a design ahead of it's time. Back during the 1970s, nobody really was looking at a twin-engine widebody jet, they were either buying the 747, the DC-10 or the L-1011. When MD proposed the DC-10 twin jet, there really was no demand for it, and the project got shelved.

Jan 25, 2019 · There were after all quite advanced plans for McDD to make a twin of the DC-10 which could have killed a hefty chunk of 767 and A300 sales, but Douglas didn't jump. The McDonnell Douglas story has several similar events where the company made the wrong decision or failed to invest in products.For an OEM with such a strong and loyal customer ...

Jul 10, 2006 · That DC-10 Twin picture is with CF6-6 engines; I think it would've stretched (in typical Douglas fashion) to something looking more like a DC-10, given CF6-50 engines. Local history has it MDC only had enough money for one project: the DC-10 twin and the F-15 (internal development phase for the F-15, of course!).

Aug 28, 2020 · ETOPS was a major consideration, yes. In addition, while it was possible for the DC-10 to have been powered by two engines, the engines of the time meant that such a design would not have optimal performance, particularly at high airports like Denver or short runways (indeed, these two conditions were one of the main reasons why the DC-10 and Tristar were twin-engined even though the Tristar ...

Jun 8, 2005 · The DC-10 and MD-11 are robust airframes but are systems nightmares, what with cable drum slats, hydraulic lines all run through the tail (DC-10 pre crash) and bad cargo doors. Douglas built great airliners (DC-8 and DC-9 are both elegant workhorses) and Mr. Mac built great fighters (F-4, A-4 ect.) but McDonald Douglas missed the mark on its ...

Aug 16, 2010 · The McDD internal designation of D-969C was given to the project, although it was always known as the DC-10 Twin. McDD worked on project from before the first DC-10 flight, and continued to refine it until the project was canceled in 1976. It was offered to all airlines, the most interest came from Allegheny, Delta, Swissair, Iberia and Eastern.

Mar 31, 2020 · Which is why the L16 and DC-10 Twin proposals were shortened barrels closer in pax capacity to the 767-200, but with more airframe to haul around. The object wasn't even long haul transoceanic (ETOPS was little more than theoretical, at that time), but rather year-round transcontinental USA... barely realistic with the A300B4 and a non-starter ...

Jan 10, 2007 · The DC-10 was originally proposed as a twin-jet, but airlines were concerned with performance issues (engine out, over water routes) and so MD went with a tri-jet. They still clung to the idea of a twin, proposing a shortened DC-10 with two engines to enter service in 1975, but they decided it would then compete against the DC-10 in some cases.

Dec 5, 2023 · The aforementioned article in Airways also includes artists' conceptions of the DC-10-61 in Transamerica and Laker colors and the DC-10-62 in Swissair colors, as well as an image of the DC-10 twin (which was an A300 sized version of the DC-10 McDonnell Douglas considered building in the early 1970s) in North Central colors
