I work on roofs frequent enough. Will it give proper height and depth perception? I mean, 50 feet is like 15 meters, shy 5 stories commie block, nothing too special. And I'm 100% sure that non-buttery landing won't be particularly dangerous, since 50 feet is not much, in worst case scenario it would be 60 km/h (300m=mv2; 300=v^2 v is aprox 17) vertical speed, which will never happen, unless you managed to snap wings off.
Plane might be a toast, but natural selection won't happen.
