On May Day, just after leaving her fiancé, 23-year-old Evelyn McHale wrote a note. 'He is much better off without me ... I wouldn't make a good wife for anybody,' ... Then she crossed it out. She went to the observation platform of the Empire State Building. Through the mist she gazed at the street, 86 floors below. Then she jumped. In her desperate determination she leaped clear of the setbacks and hit a United Nations limousine parked at the curb. Across the street photography student Robert Wiles heard an explosive crash. Just four minutes after Evelyn McHale's death Wiles got this picture of death's violence and its composure.
From McHale's NY Times obituary, Empire State Ends Life of Girl, 20:
At 10:40 A. M., Patrolman John Morrissey of Traffic C, directing traffic at Thirty-fourth Street and Fifth Avenue, noticed a swirling white scarf floating down from the upper floors of the Empire State. A moment later he heard a crash that sounded like an explosion. He saw a crowd converge in Thirty-third Street.
Two hundred feet west of Fifth Avenue, Miss McHale's body landed atop the car. The impact stove in the metal roof and shattered the car's windows. The driver was in a near-by drug store, thereby escaping death or serious injury.
