The SkyRocket project lasted a few months, in Mountain View CA, in 1990. I worked on it for Gary Hudson. Tom Clancy was the financier. It was a single stage to orbit, unassisted, spaceplane. We were building a prototype, but were 'all thumbs' as they say when it came to graphite epoxy aircraft assembly. Our team members include Jim Grote, Marvin Horton and Dave Hoerr. And, of course, Gary's wife, Anne Hudson. This was 3-4 years before Bevin McKinney joined our team. Anyway, once we realized how inexpensive the SkyRocket was, off the shelf engine and graphite epoxy vehicle construction, we canceled the project. And returned the unspent money to Tom Clancy, with the apologies for our lack of aircraft construction competence! You can see an artist's render of the SkyRocket here:
