Every time I try to pass near the islands of England, even when I use a TC of 128, planes keep appearing. It's a bit frustrating if we talk about starting a campaign in 1939, is necessary to navigate submerged during the day. And if the skies are cloudy usually appear in the middle and short range. The consequences: several damage to different compartments and many wounded.
Using the NYGM, someone has the same problem?
