Dude I can totaly relate to this.. I've made some very memorable goofs in my vitrual sub career.
Way back in the early days of the DC/SH2 interop and PM release i was playing an online game (Good old WPL days eh?) and after a sucessful torp kill on a destroyer surfaced with my broad side less then 100m from the bow of a destroyer coming at em at top speed, definately not my proudest moment.
i once while playing drunk clicked on the depth guage to surface a little too far over and instead of zero it went to max depth but since i imediately switched to the sonar room didnt notice, after a few minutes playing with the sonar set scanning for any potential victims heard that nerve racking warning "were below test depth" -BOOM-
