If I am reading the aircraft rules correctly, an aircraft can move across a corner from your deployment zone and go off-board on one of the side edges on the first turn; then return on the second turn on the far edge and exit on your opponents back edge; and then come back in on the third turn anywhere along your opponents rear edge and drop as many bombs as they have that same turn? Is this magic movement maneuver legal?
That is the first idea that came into my mind as well when I read the aircraft rules, and it seems pretty legal to me. Although I think it might be enough to return in the second turn on the far edge of one side and start your bombing run from there, killing whatever is on that flank.
The rules and the strategy seem solid, but it would be a pity if EVERYONE would do it this way in the future (especially with aircraft being released for the other factions). I don't like games too much where you are forced to play the mechanics, which in this case would mean to employ all your aircraft on the very edge of your DZ as you described, your opponent does the same, then both players exit all their aircraft on the side in turn 1 just to bomb the smack out of each other in turn 2 or 3.
