Spencer Lisenby sets new World Record speed for a Glider of 357mph. This vid shows the 333mph pass but vid camera battery died before the 357mph run. Thanks JOe Zepeda for video.

  • Actually, altitude ...

    Actually, altitude plays almost no role in building the speeds here. This is not a simple trade off from kinetic energy to potential energy (speed or altitude). Dynamic soaring relies only the velocity difference between the air on the front of the slope (40-50mph wind) and the air on the back of the slope(+/- 0mph).

  • Outstanding work. ...

    Outstanding work. Even for the videographer. And radar man.

    For the disbelievers, this sailplane is "powered" by the sun. Really. Sun causes wind, wind hits mountains and is curved up. The vertical component of this wind provides the energy to lift the plane, counteracting gravity. Flying orbits, it COULD climb until the wind no longer curves up from the mountains. Instead, the pilot keeps it in an orbit, varying the altitude to maintain the energy. Speed or altitude.

    Ahh, good. A speed demond can go slow :)

    How fast do the flaps slow it down?

    The plane is equiped with flaps to slow it down for landing. It can 'hover' in about 35mph of headwind...
