This is Science Today. A hypersonic aircraft that
can travel ten times the speed of sound by skipping
across the atmosphere, has actually been designed
- but it'll be a while before passengers can book
quick flights across the globe. Aerospace engineer
Preston Carter of the Lawrence Livermore National
Laboratory who designed HyperSoar, says that's because
there are several logistics that need to be worked
Carter: HyperSoar is a long, slender shape.
Engineers call it a wave rider and it's kind of an
interesting shape in that a wave rider creates a shock
wave as it flies through the atmosphere and the vehicle
actually rests upon that shock wave and rides kind
of like a surfboard rides on a wave.
Narrator: Passengers would experience twenty
seconds of weightlessness every two minutes - sort
of like being on a swing.
Carter: Some people speculate they'll get motion
sickness. That might be true. People wonder how you
move around. Good questions! I think all this stuff
is doable, but it will have to evolve.
Narrator: For Science Today, I'm Larissa Branin.
