    A lot of dreams for hypersonic but has yet to be realized. The Concorde was never a realistic passenger plane and hypersonic would seem like even more of a stretch.

    The Boeing X-43 went into space without a crew and is the fastest aircraft on record, boasting a Mach speed of 9.6. A winged booster rocket once flew on an X-43 and drop-launched from a Boeing B-52 Stratofortress.

    The rocket was eventually discarded, allowing the X-43 to fly using just its engine, which is known as a scramjet. These scramjets are able to operate at Mach speeds of 4.5 or higher.

    There are also different versions of the Boeing X-43, including the X-43A, X-43B, X-43C, and X-43D. Each of these aircraft have since been cancelled, most replaced with planes such as the Boeing X-51A, which was dropped from a B-52 in May of 2010.

    Virgin could spend its time more wisely by refunding its passengers.
