The QSRA was created in the late 1970's/early 1980's for experimental flight research, aimed at developing technology for quiet short haul commercial airliners with short take off and landing capabilities. The aircraft was remanufactured from the DHC-5 Buffalo. Boeing created an all-new wing incorporating boundary layer control, four Lycoming turbofans which exhaust over the upper surfaces of the wings and new engine nacelles and cross-ducting Coanda flaps. This made it possible to research upper surface blowing, which allowed the aircraft to fly at very high lift coefficients.
