entire legions of lawyers waiting to sue the US Government for supplying him
the wrong type of fuel?

Johanson's machine is the Ozzie equivalent of experimental, amateur
built (they recently copied the US regs on that), and more or less, he
can probably burn what he wants.

As for alcohol, as I understand it, the effects of ethyl alcohol are
confined to possible rubber (real and synthetic) deterioration. That
doesn't happen instantaneously, and I bet he could refuel with any fuel
of suitable octane, launch, and then purge the fuel system at a later stop.

As for suing folks, I don't think Jon's that kind of guy. I've met him
several times, and he's got a whole lot of class, something that many
RAHers would do well to emulate.
