I remember staying down the street at the Marriott Marquis in the heart of Times Square. It had a 40 story interior atrium with a bar on the open lounge floor at its base. As I recall, a 40 something decided to commit suicide by jumping from one of the higher floor interior balconies and landed on top of the bar during happy hour, much to the shock of the patrons sitting there.
I was a kid in 1950s NYC and one time heard of someone who was about 10 stories up, threatening to jump. From what I understand, we hadn't sunk to the level of the crowd shouting "Jump! Jump!", but all those who had cars parked in the landing area rushed over and moved them to a safer place. The Daily News tut-tutted and called them "stone-hearted".
Dunno if the guy ever did follow through.
