Hooper_X We almost used these against the Nazis, and the Nazis were working on their own version at the end of the war. Apparently, the Russians used something similar in the 60s and 70s to recover cosmonauts that landed way out in the boonies.
I wonder what this technology would do on water (I know, sink, but you know what I mean), and what if you could build one with the screws the size of tanker trucks that ate buildings for fuel... do you guys like jousting at all?
Hooper_X Apparently some dudes in Scandinavia have been doing that for a while - they work pretty well as a boat and they can climb onto muddy shores fairly well. They make pretty good fishing boats, I hear.
