Developer - Boeing designation - Boeing 2707-200 type - Hypersonic passenger jet project - 1967 Number of Passengers, pers. 2-cool-cool 300 1 - 350 In late 1967 Boeing with FAA approval, introduced in the construction of a number of changes - a model of the Boeing-200-2707. Since the change in geometry of the wing is not completely offset the shift in focus of lift when flying at supersonic speed, in addition it was found motionless PGO with control surfaces on the trailing edge. The fuselage was lengthened by 3.6 m (12 p), which allowed to place another 15 seats. But these measures have increased structural weight and drag, which led to an increase in the required fuel reserve. For some compensation growth weight has been simplified design of the bow deflected part - it was made odnosharnirnoy with a sliding flap (similar to Concord).
