The Dobbertin Surface Orbiter... That is the coolest scratch-build I have ever seen...

I'd really love to see that thing in action.

The DSO gets 12MPG and has a 340 gallons capacity, so it could go about 4080 miles, which is quite a distance to get a person out of trouble. Well, that's on land anyway. I have no idea what the MPG for sea travel is.

Cool beans.
