Truly a better time - today we worry about using Rust 'unsafe' too often. They had a smoking room on a hydrogen airship!

Our brains are becoming more plastic by volume than neurons. I'm not sure we have a leg to stand on when lecturing the past.

I imagine the smoking room was partly a safety feature. It was pressurised and located somewhere where hydrogen wouldn't leak. So you now have all of the smokers do it somewhere safe instead of trying to light up in secret somewhere unsafe.
