In systems where the metered flow returns back to the tank, I often
find the point where the return piping enters the tank a weak spot.
It happened more then once that at full test flow the tank wall is
heavy shivering, despite the reinforcement of the entrance point with
additional steel.
After years of testing, combined with corrosion, such heavy trembling
could cause a fatigue tear.
If that happens, water will gush out and the whole tank will move in
the opposite direction because of the reaction force.
Looking at the pictures, it wouldn't surprise me if that is what
happened in Lake Placid.
I'm curious what the results of the investigation will be.

Trust we'll hear more about this tragedy, but be forewarned. Didn't
see this up here yet, pardon me if I am repeating- pretty important.
