Hi!
I have a question about the Flak effeciency in the NYGM 2.3.
My boat was surprised by the Coastal Command Sunderland in Bay of Biscay (17th patrol and still alive

), the aircraft was visible with the naked eye so, I had to try to fight the first pass. I have 2 double 20mm's and the FLak vierling installed... All weapons fired this Sunderland flying over us maybe 200m altitude and nothing happened (the tracers showed many many hits). It just attacked, went by and returned later while I was luckily submerged.
Since it seems, that (even) eight 20mm weapons are ineffective against this large and comparatively slow and low flying AC, there is very little point to "obey" Dönitz's command to "fight against AC's" The message I recently received.
Don't get me wrong, I love NYGM and I always avoid any contacts with airplanes if possible, It's too risky and stupid to fight with them, but the "man" said I have to to do so, so...
Dear NYGM users, is it just waste of time to shoot them, it looks and sounds good but it dosen't do any good. I haven't tried the (NYGM)Flak academy (done that qwazillion times with vanilla game when it came out..) so I have no idea about the weapon effeciency.
