This may be a stupid question, but unasked it won't get answered. Is it possible to tranfer a vehicle from one ship to another in space: vehicle in YT gets transfered to another YT sitting next to it?

If not that, is it possible to transfer a vehicle from one ship to another when both are docked within a hangar?

If neither of these are possible, why?

No you can't transfer them directly.
Yes you can undock a vehicle in another one, then load it up. (or dock the first ship in the second, and then unload)
