A 29‐year‐old woman apparently jumped from the 86th‐floor observation deck of the Empire State Building last night, but survived when she landed on a three‐foot ledge about 20 feet below, the police said. She was admitted to Bellevue Hospital with a fractured pelvis.

Authorities at the 102‐story building on West 34th Street theorized that strong wind gusts — and no small amount of luck — saved the life of Elvita Adams, of 975 Walton Avenue in the Bronx.

George Reice, night supervisor at the observatory, said that a guard heard calls for help at about 8:15 last night and found Miss Adams lying on the 85th‐floor ledge of the building.

A spokesman for the building said that ordinarily four guards patrol the 86th‐floor observation deck, which is surrounded by an eight‐foot, ironspiked fence. But, the police said, no one saw Miss Adams jump. The police said they were considering the incident an attempted suicide.
