Airplane overkill?

Ok, some time ago i wanted more aggresive gameplay etc, now in 43 it's hardcore or rather HARDCORE. I'm crawling home between Rockall Bank and England, trying to fix my conn tower after one more precise bomb from hundreds dropped. With longer repair mod I needed about 1,5 hrs to fix most important things. Now surfaced 20th time? and still didn't fixed all. Looking at the map I'm in the same place. Planes come every 5 minutes? If there is a window of 20 minutes we wonder did the war just ended or what?

I understand that planes were subs greatest enemy but sorry, ~30 min underwater to loose the heist, 5 mins surface for a quick breath and fixing conn, crash dive on radar signals... Day and night! Now I've counted 6 signals, already was doing flank before dive, finally decided to crash. External cam... 2 Catalinas, 4 (FOUR) Liberators, they dropped their cargo behind my bow as it was still shallow. Didn't have time to count, it was like 40 bombs in half a minute?????? This is crazy! It looks like Tommies have millions of planes, full of bombs, searching every centimeter of Atlantic non stop. It's not the thrill if this time Tommies will be faster. No, I simply can't surface because I already know there is a plane waiting... I can go for the whole day underwater, zig-zag, either way just after surface in 80% there will be a plane. Add to this no alert when using the scope, just TC drops to x1...

In this area I was sunk 5 times now? Still crawling. I accept my errors and eat those bombs but crew shouts too late, no info through the scope, or they surface just under a plane just like that and stay quiet until we're under attack. I'm getting sick and tired of this.
