Cutaway of TV Studio Floating on Air, 1950
This TV studio in Chicago had one problem: it was located in the same building as printing presses for the Chicago Tribune. Vibration from the rumbling presses would compromise TV production.
Solution: float the studio on air.
Rubber bags, each 14 x 30 inches, were inflated and placed under the flooring. The bags elevated the floor 1/4 inch.
