Hi, i've just been trying to create a British Paradrop scenario in the editor, but how do I load the boys into the C-47's so that they begin the game airborne?
I know how to assign ground transport by selecting the infantry unit, then selecting the type of transport I want by CTRL-clicking the transport, but that doesn't work when I CTRL-click C-47's.
Also, when I was dabbling with empty C-47's they wouldn't land, the tyres screeched normally to indicate a landing, but no Hangar graphic appeared, and the C-47 stayed hovering over the airfield with its fuel depleting each turn.
Do special rules apply to C-47 operations or what?

Thanks mate, yeah we have to trigger them on, I was just about to delete my starter post because I figgered it out for myself 5 minutes before you posted, after a couple of hours of testing in my laboratory..
