I once pulled a J-10 out of my *** and went on a killing spree.
Yes i know where you mean, the first time i came across this it killed me about 5 times , always in the same place before i made my mind up to stay well away from it.
Its just as you fly over the crane and get to the sea, for what seams like no reason at all your plane blows up.
Also one on Dalian plant. Slightly northeast of the Chinese uncap. Amount of times that ****ers got me when try to escape from j-10s lol
I must be doing something wrong because I routinely crash into jets (in a jet) and other silly "what are the odds..." things but I have yet to hit an invisible wall on either of thise maps.
