The Boeing 929-100 went into service in 1975. It was equipped with 2 Allison 501-KF jet engines. It was optimised for speed and had a typical cruise speed twice as fast as its competitors at the time. It was marketed as a short range people carrier with a maximum 1-class passenger capacity of 350 and a range of under 500km. Some variants had been produced for military use.
It had not been a hit because of its high fuel consumption at 1.75t/hr. Only 39 were ever built of which 24 were built by Boeing in Seattle alongside the 727/737/757. After the conclusion of production in Seattle the Boeing 929 was licensed to be built by Kawasaki Heav Industries in Japan.
The Boeing 929 is a Jetfoil.
