Yesterday I'm returning from my first patrol. It's 1939. I was cruising along at 256x approx. 130km-170km NW of Stornoway just past the deep depth line.
Here is a summary of that day's air attacks.
Sun-up, attacked immediately as I secured from red
1st) 0630
2nd) 0945
3rd) 1030
4th) 1300
5th) 2010 (at 280km distance from nearest base)
Needless to say, It's taking forever to travel. It seems my initial estimation was very low at 1 or 2 times a day once I started writing the approximate times down.
Were these amounts of air attacks common in '39?

Also, is there a way I can tone them down a bit?
