Space Ship Two

As someone who's flown on the KC-135 "Weightless Wonder" (aka The Vomet Comet), believe me when I say that zero-g is awesome. If I had a sh*tload of money, I would defintely give this ride some consideration. Of course, as an engineer, I'd probably also let them make a few dry runs before I trusted 'em.

Passengers will have several minutes of weightlessness during the spaceflight, and then have about 40 seconds to return to their seats...
