For the record. I was just re-listening to chapter 7 where they do the sweat tests. During the scene where the zombies come up the adjacent tower that they ziplined down to, they cut the return zipline back to the tower because a zombie got on it. Anyway, angel says something to the effect that they should just starting dropping zombies three stories because it seems to kill themzombie as well asmaybe bullets. So we can assume the adjacent tower is 3 stories. So burt fell roughly 30-40 feet. Not as devastating as all that really. I'd say it would definitely be survivable.
