This retired KC-135 Stratotanker is permanently mounted and on display at Ellington Field in Houston. When it was in service it was used by NASA to expose astronauts to near the weightlessness of spaceflight. It flew in a parabolic pattern, climbing at twice gravity to the peak, then falling. This repeated exposure to several seconds of two times gravity followed by several seconds of no gravity made most people motion sick, thus the nickname vomit comet. More official names are "The Weightless Wonder" and "The zero-G trainer."

Ah, based on the old B707 design I see.

Do you know what aircraft they use now for NASA training?

Cheers, Tony in New Zealand

Yes, the KC-135 is based on the Boeing 707.

I've been away from this for many years, but I think they may be using a modified Boeing 727-200.
