and, you had to do this twice.
does that seem reasonable, even feasible, to you?
Reasonable, that would depend if you can benefit in some capacity with the buildings be knocked down. Feasible, yes. Knocking buildings over are not a difficult task.
I'm not an expert on the demolition of buildings; although, I suppose all it would take are charges on the main support pillars. Let's say every other floor or every third floor.
I did see first hand how a professional fireworks group shoots off fire works on the 4th of July. It was a large panel 4' x 2' with multiple many switches. They also had 2 laptops tied in some capacity. After it was wire-up all they do is hit the switches in the proper sequence.
