Ronster, while ben_danger uploaded those videos, he didn't create them...they were actually the work of a guy called SSWR I guess, who apparently had lots of great ideas, and then vanished, as did his videos over time. I think they are "public domain" so to speak.

As for the shuttle, I honestly don't care if it changes or stays the same, but I do find some of the alternate ideas interesting. I agree, bat wings may not be the way to go, but making it distinct and more powerful looking could go a long way--perhaps just arming it with some big guns or something.
