There was a startup like 20 years ago trying to get them to be used for trucking/shipping purposes iirc. Guess it didn't work out. If used with hydrogen instead of helium, that can be more cost effective. I've only seen the Goodyear ones a few times when some kind of sportsball event is happening in the metro.
Supposedly they are constantly getting shot at in the states. I recall seeing some docu show where one of the pilots or maintenance folks mentioned finding small holes in them quite often after flying around.
