CHICAGO (CBS) — The “Ledge” at Willis Tower has a new rival for skyscraper thrills in Chicago. The Hancock Center has its own gravity-defying feature, “Tilt,” which lets visitors lean out over the edge of its observation deck at a 30-degree angle.
For an extra $5, visitors to the Hancock’s 94th floor – now dubbed 360 Chicago – can walk into a steel-framed box that gradually tilts eight people at a time to a 30-degree angle toward the ground – more than 1,000 feet up in the air.
John Peronto, a structural engineer on the Tilt, said the wind speed at that height was one of the most critical obstacles to overcome.
“As the Tilt system moves in and out, there are three piston-like devices that push the actual steel frame outside the building about 50 inches, give or take, which creates the rotation of 30 degrees for the occupant,” he said.
