The Biggest Rocket ever Designed? - The Sea Dragon

I think that everyone has been thinking about re-use for a long time. The Space Shuttle was supposed to provide economies through re-use of the vehicle though the boosters were thrown away. Sadly, it was so expensive to refit the Shuttle, there wasn't much economy there.

This is why I set aside a few minutes every day to "leaf through" the Internet without searching for anything in particular. As a child, I used to do the same with encyclopedias. One of my favorite "leafing" tools is StumbleUpon which is a search engine with only general parameters. You select categories and then let StumbleUpon randomly show you things in which you might be interested.
