zero gravity coaster article

In the Feb 2012 they have an article about building a zero gravity coaster. It would give up to 8 seconds of zero g. Of course the design is basically the S:TE looking ride from Six Flags. But this would be an enclosed vehicle (looking like a shuttle in pic). It really does not look like much more than the existing S:TE but would allow people inside to wear loose fitting belts and float a little during the experience.

Who is "they?"

My bad....This is in the latest issue of Popular Science
