What got me thinking was I was going to try to build my own landing pad and I like the old one (looks like a pizza dish) that
GW used in photos. I was going to put an elevator in because you have to be able to move the cargo off and to the camp. I was thinking of having that like the elevators on an aircraft carrier where it is basically a large lift that moves planes from the hanger to the flight deck.

This is one in action bring up an S-3 and an F/A-18.
I started thinking about why the US military doesn't build platforms and then realized it is just easier to have it on the ground. No climbing ladders to get to the aircraft. No difficulty in getting fire fighting equipment to it in the event of a crash or malfunction. No weird logistics in trying to rearm.
This in a game with giant bugs, killer bipedal fungus, Elves in Sppaaacce, and chainsaw swords. I need to just accept it. LOL
My wife suggested an ornithopter instead of the balloons. The said the cockpit should look like a giant brass eagle head (bugger all if I know how to build that) and with exposed pistons to pump the wings up and down.
