If you know anything about hydrogen, you understand that sabotage was completely unnecessary.
Hydrogen is a highly explosive gas with practically no lower explosion threshold. Zeppelins were used and abandoned in WWI because slow moving aircraft didn't even need to fire real bullets at them. One phosphorus bullet and it was toast.
Static electricity prevented them from flying if the humidity was too low.
And why do you think they grounded them when a thunderstorm was anywhere on the horizon???

History is littered with attempts by some businesses and governments to ignore the laws of physics, and the warnings of engineers and scientists. And I don't mean media portrayal of science either. That is even worse.
