I took this picture of the Bell Zero-G Belt October 6, 2006 at
The Niagara Aerospace Museum.

The Bell Zero-G Belt has a number of small rocket engines designed to allow an astronaut to maneuver in weightlessness. It's powered by compressed nitrogen stored in a series of curved tubes around the operator's waist.
