Airships are possible but they have a unreliably due to being at the mercy of weather and wind conditions combined with helium being an extremely finite resource (already running out, exponential price increase) that is not renewable

you know I think you probably could do hydrogen airships with modern safety standards. It's flammable and "leakier" than helium but planes and cars are also full of flammable and/or explosive fuel and we manage that part well enough
