I found this in my FSX, as I have FS global 2010 in and a friend I know does not, I can verify this is a fault with fs global as he does not have the issue.... BUT WHAT A THING!!
I flew over it a few times before doing a controlled stall down into it. When I eventually reached the bottom at -104,000ft there was enough room to land smoothly, and with the air being too thick the engine wouldn't start either making it impossibe for me to get out without cheating. It is 15miles From ETNN on a heading of 300
