At the risk of starting yet another thread about foolish adventurers, this story is not about fuels, it is about fools.
That idiot flew to the point where he had to say, "Save me!" A nice trip home is quite satisfactory, and let him bring his factory/home/kit built home as a kit.
I spoke once to a Coast Guard pilot who expressed his exasperation at risking his life to fly way offshore at night to help yet another ill-prepared fool who simply KNEW somebody would save his sorry ass after he had painted himself in a corner. The Coastie said they would like to have permission to drop the emergency pump from 500 feet to help Darwin.
Regarding the saving of this Antarctic fool, the press that he now generated should help stave off the thousands of idiots who would try it, too, if they knew someone would "rescue" them when they, too, failed.
