Generally speaking, most aircraft delivered cargo in WWII involved the plane actually landing to unload it. An air drop requires the cargo to stay under a certain weight so that the parachute can deliver it safely to its target, so realistically you should be able to deliver more weight if you planned on unloading it on the ground. I'm not saying we should get rid of the airdrop option, I just want to see another load out for the goon that would involve unloading it from the aircraft after you've come to a stop either on the runway or a specific part of the airfield like an assigned pad or something.
