It would take way more than your hour just to get the cargo there, and then load and secure it. So the only way is to have the cargo already secured on board.

You still have to lift, seat, and fuel the can. It will necessarily be scrapped after the one use, so claiming it ahead of time doesn't cost any more. It could be customized for the job, maybe with missile ports ranged around the belly. I figure a minimum of six hours from "go" to a container on the ground. Maybe it delivers a whole truck and load. Or one main battle tank. (An F-35 wouldn't fit.) Longer if you want crew.
