Hydrogen is denser by weight, but by volume the story is completely different. The tanks need to be large.

What if most of the aircraft was hydrogen tank or bag? Then it could use the hydrogen for some of its lift! We can call it an "airship".

Or compress the hydrogen, but then you have 700 PSI handling issues and the tanks have to be very strong.

Yeah, let's make a huge one and call it the Hindenburg! That sounds like a foolproof plan.

Too bad that there hasn't been decades of materials science improvements, including and in particular to handling flammable materials, between some highly propagandized disaster and today.~

(Almost every modern cruise ship is bigger than the Titanic, imagine if people acted like the Titanic was the last word on how big a cruise ship could get.)
