About landing planes:
Air units have only their movement point allowance (Fighters 4, Bombers 6 ) to spend during the entire turn. Planes do not have to land back in the exact territory (or Carrier) they came from. When you move a plane into combat during the Combat Movement phase, you must remember (or use the included Flight Markers to indicate) how many points of its movement it used to get there. Then, during the Noncombat Movement phase, any surviving planes must use the remainder or (or as much as they need of) their movement points to move to either a friendly Carrier (Fighters only - Bombers can never land on Carriers) or a friendly territory that your side has controlled since the beginning of your turn.Â
You must be able to prove that such a safe landing spot exists during the Combat Movement phase (or that such a spot will exist once you move any Aircraft Carriers into position during your Combat Movement or Noncombat Movement phases) in order for the plane to legally fight in the combat.
For example, if I fly a fighter 3 spaces to fight in an enemy territory, I have only 1 movement point left for that plane to get to a legal landing spot.
EDIT: I put Bombers movement as 8, fixed it to 6
