Bringing Back Zeppelins ???

Here is a puff piece about a company that wants to build hydrogen-filled airships:

I have always been fascinated by zeppelins and envy those who got to fly in the Graf Zeppelin and Hindenburg. Apparently, so is Google co-founder Sergey Brin:

Here's something to keep in mind - apart from the Hindenburg disaster, the main problem with large airships is that the atmosphere is unpredictable and their large cross section makes airships prone to being tossed about by wind shear and other air anomalies. If that problem doesn't get solved, these new airships will never be a thing. They'll crash just like many of the original ones did.

And going 175 mph? Good luck with that.
