The Advantage of Airships
FIrst, they can scale up to infinite weight capacity. So the US Military has a few ideas about transporting whole battalions on mega-sized airships. Most importantly, barring winds that would also knock helicopters out of the air they can land anywhere.
So if you're a military commander fighting an insurgency the advantages become clear right away. Do you try to secure and hold an airport with its easily vandalized runways, roads leading to and from that can be mined or lined with snipers, and deal with all the trucking and escorts? Or do you just drop several hundred tons of stuff wherever you want?
Likewise, if you're Walmart which approach do you prefer? Do you deal with cargo ships and containers, and trains, and trucks, and all the steps involved in moving dozens of containers from factory, to train, to ship, to train, to truck, to distribution center, to truck again? Or do you park a great whopping airship over the factories, winch up a mega-ton of stuff, and then coast over to the regional distribution hubs and drop them right there? You can't do fresh produce that way, but it makes sense for most other things. Well, given the time consumed moving stuff from one form of transport to the other it might be faster...
Foreign aid agencies are also mad for this idea. Using airships they can bypass bottlenecks like airports and sea ports that are often controlled by corrupt governments and airdrop stuff directly to those people who need the stuff.
