The winds were so strong in downtown Seattle, a crane looked more like a spinning top.

To some it looked scary, but they had to stop to look. "I usually watch the cars when I cross the street, but I was watching the crane because I was nervous," said pedestrian Bridget Quigg.

Even construction workers looked up. You don't see this every day.

Believe it or not, this is normal. In high winds, this spinning is normal for the particular type of crane being used at 5th and Madison.

The only problem: a long chain hanging the crane. As the crane spun, the chain whipped out. "The chain from the crane did strike the side of the Bank of Cal building," said project manager, Scott Holbrook. It hit the building several times, smashing four panels of decorative glass.

The glass fell into the construction site during the early morning hours. No one was injured. When the winds died down slightly, a crane operator lowered the ball and the chain was removed.

The chain hit on the 38th floor where Jamey Grigsby works. "I heard clinking of the chain actually hitting the roof top right here," he said. "And sometimes I would hear the clink as it hit the crane itself."

Attorney Franni Turean got the view from the 32nd floor. "It looked like the exorcist, it was spinning and spinning, you looked up and you could see the chain that was swinging out and we weren't sure if we should stay or leave," he said.

On the 29th floor, you could see the whole crane swaying. "We were so scared we had to watch the entire thing," said Cheryl Delaittre.

Turner Construction says this crane and others it is working in the Seattle area will get a full inspection.

The State Department of Labor and Industries told KOMO 4 News a recent crane collapse in Bellevue and cracks found in two other cranes on the eastside have focused attention of cranes statewide. They expressed confidence all cranes will be checked throroughly after the current series of windstorms.
