I've not had any crashes as yet, only on my second trip of a career using GWX, but did have a fright on return from my first trip.
I was returning to Whilmshaven, arriving under cover of darkness, when the shore batteries opened up on me & killed 4 of my deck crew

I've heard of 'Friendly Fire' by Americans, but these are German, What the @#*@ is going on there ?
