My comment about the MSA was a bit tongue in cheek...
I actually know somebody who did "land" in the top of trees, having flown into a valley in some very poor weather and found themselves cut off by low cloud in all directions. The "landing" was successful but after a brief moment the aircraft crashed down as the branches gave way and some if not all of the people got pretty nasty injuries.
There is a number of videos out there of people flying into terrain. Low flying, especially among significant terrain, is a thrill for many but evidently not all of them know how to do it right. I did once go on such a flight with a local pilot in
Switzerland and that was great, but we were always able to climb back out.
There is a well known case in the USA where 3 Bonanzas (IIRC) departed down a canyon, one behind the other, and all three crashed into the end of it. All that was left were three triangle-shaped piles of ash.
