When demolitions experts bring down a building they look at the architectural drawings, hall of records building site plans, measure the building etc...
If the building is 200 feet tall you can assume they set up their command center lets say.... more than 200 feet away?
Apparently this sort of planning is not taught in veterinary school since this Vet tranquilized a horse and stood next to it waiting for it to fall over.

I assume this happens 50% of the time.
