Adding more bombers will cause problems if there are not enough people online.
I don't know if it's possible but if we could link the bomber numbers to the player numbers it should work perfectly fine.
The escorts only spawn if there are no P51s on the map. However, if the server is emty enough bots spawn overall to get constantly into so action.
Putting the bombers to an historical altitude would also mean that players would have to spend more time climbing to that altitude :/
I think we should make a poll about this, if enough players are ready to check the missions current status.
