I think that with DLC festering skies we got simple and pleasant aviation mechanics, but it seems too detached from the main game, the ability to use the plane in tactical missions, depending on its equipment, would connect the DLC with the main game, giving us the opportunity to feel the DLC not as a mechanic torn out of the game, but as a full-fledged part of it. Perhaps something like the American AC-130, which once in a mission will arrange hell for the enemy to the musical accompaniment of the flight of the Valkyries.
