Indeed the planes are just.. maybe remote controlled
I was sneaking in a harbor, sinking a merchant, but the destroyers chased me with asdig.
I was surprised because no depth charges were used, instead i was on 20m and the destroyer rammed me. I was suffering heavy damage. Using the exterior cam i saw there were over 2 meters of free spave between the DD keel and my upper point of the bridge...
But it rammed me anyway.
