they really arent, i remember reading a reddit post chronicalling how there are only 150 living people that know how to even operate a blimp. they are like on stand by and its their side hussle. they hold down normal jobs like mechanic or logistics administrator and then they get called to run the good year blimp for a weekend.  this is a rare breed and its dying out. no one gives a crap about blimps and airships
