Hey -Z-
Maybe you should add some info about a colony drop to your High Frontier web page?

I know this all just anime physics, but would a colony even survive
re-entry? Colonies strike me as being rather fragile. Over half of their
surface area is windows, which I cant image were ever designed to stand much
heat. Just my 200 yen.
