Hi guys,
The Harbour Traffic mod only adds
one scripted air attack in some ports (that attacks with only one pass). The other attacks in ports are a SH3 random instance, not made by the mod. The Hurricane in Wilhelshaven it's because it's early war (1940) and you don't have much options about air units on SH3. I know that this is a little unrealistic way but is for fun too. If you don't like air attacks just get the harbour traffic mod for Rub which is without that air raiders.
