You make a good point, but would it have turned out better if the Hindenburg had been full of gasoline?

Well, it would have never left the ground, for one :)

Do you remember the bathyscape that set deep sea records back in the 60's and 70's? It was essentially an underwater dirigible with the float filled with gasoline instead of hydrogen. The gasoline being lighter than water but still incompressible allowed the craft with only slightly negative buoyancy to go slowly to the bottom. When they wanted to come back up they just dropped enough ballast to become slightly positively buoyant. That is just an aside, though. I'm sure you got my point that gasoline is not that much safer than hydrogen.
