That would definitely do damage to somebody's skull.
Airspeed, drag, and terminal velocity and all that I would assume it's going subsonic and appears to be quite brittle.
The angle also appears to be consistent with what I've seen other impacts produce in the 40 degrees.
The lack of sonic boom and camera catching it I am curious if this happens on the daily with nominal observation.
Terminal velocity of meteorites is around 200-400 mph. If it hit you in the skull it could be lethal.

I love that on HN you need to cite StackOverflow to document that dropping a rock on someone's head hurts a lot.
