Let's put a billion birthday balloons worth of MRI gas in a terminally slow aircraft and inexplicably fly it over sports stadiums.
There are other gasses to use.
And that don’t readily explode when exposed to an ignition source?
(I actually think hydrogen party balloons would be fun).
lol, I worked in one (dangerous) shop where a common prank would be to wait for someone to be in thier hood, upend a large styrofoam coffee cup from the break room on the edge of someone's bench, fill it with aceteline from a torch and spark it.
I’ve seen that prank too. Feels like an old fabricators’ rite of passage. Also probably where a lot of cases of tinnitus originate.
100% hydrogen isn't explosive. It's only when about 30% of oxygen is mixed does it become dangerous.
Modern airship designs can go hundreds of km per hour.
With modern technology we also can contain fire into pockets.
This isn’t much different than criticising a plane because petrol is flammable.
Yeah, no. I'm back at a real computer and thought about this so I went and looked.

Guinness World Record is 115 km/h, a blistering 72 miles per hour.
That's a stripped down machine made for "speed". Anything made for "work" is going to be considerably slower. Don't get me wrong, airships were an important stepping stone for aviation but none of them can compete with an airplane for utility.
Wait, what? I'm in my phone at work so searching sucks, can you link one of those fast airships?
The Hindenburg with 90 year old tech had a cruising speed of 122 km/h.
woah! Everyone hold on to your hats!
