We're right under the flight path for the scheduled orbital launch, but don't worry--it's too cold out for the rockets to operate safely, so I'm sure they'll postpone.

Surprisingly, if you google "hydrogen airship revival", you will find that there are many companies trying to build airships.

Since the non-flammable helium has less lifting capacity and is non-renewable and expensive, they are trying to use hydrogen safely. Good luck...

Armchair pseudo-scientific thinking like this was why Mythbusters became so popular. They even devoted at least one episode to this very myth. Spoiler, hydrogen wasn't what made that particular lead ballon unsafe.

I didn't particularly like that episode because they didn't do another control test and just called it a day
