Reading through the official Carrier news thread and it seems pretty common for people to be conflating "16 landing pads" with "16 ships" to the point where, honestly, I'm not sure if they're just assuming 16 pads = 16 ships or whether they've noticed something (some text in the video, perhaps?) which does actually say "maximum storage: 16 ships" or something.
As I pointed out in a different thread, I think, I notice that the services provided by Carriers are all stuff we can currently do, at stations/platforms, without entering the hangar.
Also, FWIW, although the video shows pads rotating several times, I don't think the video ever showed ships lowering down into a hangar.
That might indicate that there are no actual hangar facilities, at all, on Carriers and you just park ships on a pad and never leave your cockpit.
OTOH, you'd think it'd be easier to simply have pads operate in exactly the same way they currently do so they could make use of the existing code related to how they work.
I get the feeling this is going to be something where I get tired of saying "Do you have a source for that?" by December.
