I do remember that many years ago. However its a rather extreme example.
We do use hydrogen on busses and they seem to think that safe enough with
a bus load of passengers in London. Hydrogen burns with an invisible flame
most of the time. That is one reason why a small hydrogen fire was not
spotted in the old airships until it was far too late of course.

AIUI, the Hindenberg deaths were mostly caused by people jumping out of
the gondola. They should have stayed in it until it sank down to ground
level and jumped out.

And got burnt to a crisp as the whole thing came down on them in flames.
