I played the Blues Bears 'A needle in a Haystack of Oceans' PPG at Carronade on Saturday.
The scenario is a costal command Wellington patrol designed to spot U boats, enemy shipping with the possiblity of air to air combat against JU88s or a Condor.
On my patrol all I saw was a passing Wellington returning from patrol.
99.9% of these patrols saw no enemy activity, so it was highly realistic
