How a Skyscraper Window Washer Faces Death


HAILED as supermen, stunt artists are paid fabulous sums to risk their necks for a thrill-hungry public; yet their most hair-raising feats are duplicated every day by the daring men who clean the windows of the nation’s towering skyscrapers.

Perched at dizzy heights on window ledges barely wide enough to afford a toehold, the aces of the window brigade put circus acrobats and parachute jumpers to shame. For there is no margin of error—no nets or parachutes to break a possible fall. An error in judgment, a slip of the life belt and the window cleaner has signed his own death warrant. Below him there is nothing but a yawning city canyon—a square of concrete pavement to land and die on.
