Launch HN: Buoyant (YC S21) – Blimp drones for air...
Someone else mentioned the prevalence of vandalism against trains crossing the country, and that all too many trains arrive at their destination with bullet holes. A hydrogen-filled blimp would be a tempting target for people so inclined.

A train is a giant piece of metal they can hear the bullet hitting. There's no sound reward to shooting your gun into the air, maybe hitting a blimp.
