@RegDep
Thanks.
If you look at the end of the runway near the ILS in the photo you posted you see very clearly that the gap between the runway and the ILS is
dirt as opposed to the photo by
Kulverstukas where it is
grass. The simulation of accident as described in the video from the "custom official" also indicates the surface was dirt.
But if you look at the initial video posted by
ErwinS it certainly looks like grass to me at the end. Especially so when you compare the side shot with the end shot as posted
by Kulverstukas in post #51. But the videos are grainy and it's hard to to say with certainty.
