Can the wind knock over the Space Needle?
The first manager of the Seattle Space Needle, Hoge Sullivan, was acrophobic – fearful of heights. The 605-foot-tall Space Needle is fastened to its foundation with 72 bolts, each 30 feet long. The Space Needle sways approximately 1 inch for every 10 mph of wind. It was built to withstand a wind velocity of 200 miles per hour.
