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...

I don't think airship travel is viable due to inability to properly steer them outside of very specific conditions, regardless of the filling. I would love to be proven wrong if it were somehow economic for shipping, but I have no high expectations.
