About 2 degres seperation, one torpedo hit in the center the other two missed behind the target by a pretty big margin.
The first one got there alot faster than the other two.
I was 90% sure that all 3 doors were open, but I have searched this forum and I seems to be the only one with this problem, so now Im only 70% sure
.
If tube 1 was open and the other 2 closed, the effect would be similar I guess.
