Did you know that the notoriously flammable Hindenburg airship had a smoking room? Passengers could only get to it through an airlock door. But yes, the hydrogen-filled Hindenburg had a special room where people could set sticks of tobacco on fire. (1937)
Do you really think that they didn't design the room to safely allow smoking? All airships of the time had smoking rooms and not a single one was lost because people smoking in the smoking room cause a fire. Oh wait, it is more important to be ironic than factual.
