Placing an aircraft on top of that empty carrier (was this intended?) stores aircraft in question in one of its cargo slots. But the aircraft is also visible in the cargo slot of carrier it take off previously. So in two turns one can make and illusion of nine aircrafts on all of tree carriers instead of six preplaced
. Alas this is just an illusion because when aircrafts fly off the deck there are only six of them in the sky and their clone ghosts stay in cargo slots and one can even select them from there. So one can select one and the same aircraft flying in the sky trough several cargo slots on different carriers.
