Argument: Hydrogen was not responsible for the Hindenburg explosion
Arthur St. Antoine. "Hydrogen, Fuel Cells, and Reality". Motor Trend. - "Hydrogen is highly flammable over a wide range of concentrations, but upon release it rises four times faster than natural gas, whereas gasoline vapors and propane can gather in strong concentrations on the ground. These are the reasons we know that the Hindenburg's hydrogen didn't explode as commonly believed. Some of it burned, but most dispersed as proven by the 37-second burn time and the small number of casualties (also, hydrogen is nonluminous--all but invisible--when it burns). The fuel content of the Hindenburg's hydrogen was equal to 18,000 gallons of gasoline--imagine that explosion!"
