Let's say "it already has a track record in aviation" instead.

Don't worry, nothing could ever go wrong with pressure vessels filled with heavily compressed explosive gas, especially in an accident.

Of all the explosive gases, hydrogen is not the worst. It floats, and it's combustion products tend to be less toxic. I really don't think rocketry experiences inform commercial aviation choices.

Has the hydrogen storage associated with spaceflight been responsible for significant explosions. Flight vessels are made as thin walled as possible for a reason. Land bound containers don't have the same weight penalty.

Thus, don't compress it.

Bring back Zeppelins?

Current discussion focuses on liquifaction, which enables transport without high pressure.

Funny that while you are saying this, Teslas are catching fire spontaneously.
