How cool is that, I have never seen something before.
A normal hang glider with some kind of "lawnmower engine" are flying here a lot. But I've never seen one with a rubber boat mounted to start and land on the water.
With the additional weight of the rubber boat, maybe the engine of a 747 is not that wrong and well motorized. :-D
Yep, that's quite a ballast and not a very streamlined one. According to the noise it made the motor seemed to be pretty strong indeed.
