Yep. If it was going to happen, it was going to happen on 18. 2 different NIGS almost right next to each other, and lines that are very difficult to see. Hopefully there isn't too much damage, to aircraft anyway, I'd say the ego will suffer.
It's also a bay that mainline 737's hardly use in normal circumstances, 787 and A330 do, but the 737, hardly ever.
