bc place deflated
The BC Place is the central stadium for the 2010 Winter Olympic. It would host the opening and closing ceremony. It is also the largest air support dome in the world. Two fans operate 24 hours to pump air inside the dome, creating a higher pressure than outside, inflating it like a balloon.
On the day it collapsed, the wind was blowing at around 70MPH. But the wind didn't destroy the roof directly. It was the fan inside the dome. The wind created a temporary vacuum on the roof, causing he pressure to drop. Since the fans were controlled by the pressure sensor inside, it has no way of telling what the pressure was outside, so they continued to pump air into the dome. As a result the increasing pressing blew up the balloon, causing the roof to collapse (the source of this explanation is rather dubious, believe it at your own risk.)
It was supposed to be fixed today, but it was still deflated in the afternoon.
GM Place has a hard shell so it's not damaged by the wind.

ON 8/9 AUGUST 1944, THE BRITISH,COLUMBIA REGIMENT (DUKE OF CONNAUGHT'S OWN), THEN DESIGNATED 28TH CANADIAN ARMOURED REGIMENT, WAS COMMANDED BY LCOL D.G. WORTHINGTOIN IN HIS TANK "BOSS". IN SHERMAN TANKS SIMILAR TO THIS ONE, THEY FOUGHT A HEROIC 14 HOUR BATTLE ON HILL 140 NORTH OF THE TOWN OF FALAISE, FRANCE. WHEN THE BATTLE ENDED THE "DUKES" HAD SUFFERED GREAT LOSSES, INCLUDING THEIR COMMANDING OFFICER, TO OVERWHELMING ENEMEY FIRE. THIS TANK IS DEDICATED TO THE MEMORY OF ALL THOSE WHO FOUGHT SO GALLANTLY ON THE HILL TO PRESERVE OUR PEACE AND FREEDOM.
In 1878 on the approach of an enemty cruiser squadron these 64 pounder muzzle-loading naval guns were hastily shore moundted to protect esquimalt. Subsequently they were issued to No. 5 Battery B.C. brigade of garrison artillery, the first citizen militia unit in Vanocouver. That historic battery became the present British Columbia regiment (Duke of Connaught's Own).
I forgot the name of this green dome, but it must be historical.
the foundtain under the BC Hydro building was frozen. The January temperature was still sub zero.
