Ask a vertical-transportation-industry professional to recall an
episode of an elevator in free fall—the cab plummeting in the
shaftway, frayed rope ends trailing in the dark—and he will say that
he can think of only one. That would be the Empire State Building
incident of 1945, in which a B-25 bomber pilot made a wrong turn in
the fog and crashed into the seventy-ninth floor, snapping the hoist
and safety cables of two elevators. Both of them plunged to the bottom
of the shaft. One of them fell from the seventy-fifth floor with a
woman aboard—an elevator operator. (The operator of the other one had
stepped out for a cigarette.) By the time the car crashed into the
buffer in the pit (a hydraulic truncheon designed to be a cushion of
last resort), a thousand feet of cable had piled up beneath it,
serving as a kind of spring. A pillow of air pressure, as the speeding
car compressed the air in the shaft, may have helped ease the impact
as well. Still, the landing was not soft. The car’s walls buckled, and
steel debris tore up through the floor. It was the woman’s good
fortune to be cowering in a corner when the car hit. She was severely
injured but alive.
