It seems to require a vacuum to spin. And then it needs to launch at Hypersonic speeds and then meets atmosphere. Instant encounter with a solid barrier == blow-up. I am thoroughly skeptical about the technology both on the incredible G forces, and then hitting atmosphere at huge rates of speed.

Earlier quoted context omitted.

I loved Heinlein as a kid... I wonder how many geeks today realize he's the origin of the term 'grok' ?

A lot? It's not that big a secret, if the question ever occurs to you. I've known for a while and haven't even read the book.

I don't think its a secret, but I do think it was before a lot geeks time...hell, it was actually published almost a decade before my time :-P

P.S. It also appears 'grok' has fallen out of favor over the years. It's too bad, I always liked how subtle it was - the distinction between knowing WHAT something does and WHY it does it(eg fully understanding it)
