I deactivated ultimate terrain,the collision remain.
That would only means UT is not the problem. It's probably another scenery you have, then.
When i load the Plane (Pmdg MD-11 or others) on Runway 27R then the Plane crashed immediately. But there is no Wall or something. I crashed with an invisible Ghost
I'm sorry but, as I've said, I've checked many times by now, and it doesn't happen. Right now, we have just you 3 guys, out of several thousands that downloaded KFLL so, you need to just find what you have in common that is installed on all your machines.
The first step to having even the slightest HOPE to fix something, is being able to reproduce it and, right now, I've been able to see this on my own machine.
I have all your Airport..all function perfectly
Not all of our airports are located in the same place so, what is affecting KFLL, can't affect the others.
