I'll second that 'welcome'. Had a big fat merchant within 2000yds , perfectly lined up and.......
Adjust spread 1 degree left.."fire one".
Adjust spread to 0 degree.."fire two".
Adjust spread to 1 degree right.. "fire three".
Torpedoes running fine, I was able to zoom out and watch them grinning and thinking "you're mine!". Heading right on the money towards the target when suddenly, short of the target....BOOM +big splash, followed a few seconds later by BOOM +big splash and the third JUST missing the stern but definitely close enough to have gone off magnetically. Merchant continues on his merry way albeit with a few stress cases on board no doubt. AAAAAARGHHH!
