BC Place: Stadium Refurbishment | Completed

[towerguy3]

Yes it was a controlled deflation. What did you expect them to do, leave the roof up indefinitely with air blasting out the hole and the roof bopping up and down with speakers and lights swaying back and forth and falling down??!

With 60,000 people inside, I'm sure the plan is to turn all 16 fans on full blast to blow the roof completely off the building.

Better that than the roof falling down onto people, right? Yes, that is indeed the plan.

The roof was coming down anyways as the air was rushing out of the hole, so in order to slow the drop of the roof, they turned on more fans to control the rate of drop.

Only when the roof was fully down did they turn OFF the fans.

And how do you expect them to so finely control the ventilation during Flame time when just two days before the Premier made his announcement the alarm bells went off in the control room simply due to the effect of a door being left open?

If the roof is that sensitive to pressure variations that a simple door being left open would get alarm bells ringing in the control room, I sure would like to know how you figure sucking air from the cauldron is somehow going to keep the roof from sagging.
