Stretches my belief muscles
The frame he apparently fell through would be just about big enough for an average man to wriggle through.
How come he managed to pass cleanly through without smashing himself to bits on the frame, and breaking the frame in the process (falling 10 stories he would be travelling at a tremendous speed on impact) and still managed to leave half the glass in place, albeit a bit bent? He would have had to have been absolutely vertical with his arms tight against his sides, either foot first or head first.
I fell from a first floor window sill, landed upright and broke both heel bones and both ankle joints. If I had fallen as far as he did my chin would have finished up smashed against my boots
