Here is a great article from the 1995 New Yorker which tells the story of the Citigroup building in Midtown Manhattan. This building is basically sitting on 4 pillars that are in the middle of each side of the building, so the corners hang freely.

Some time after the building was built, the leading engineer discovered that a storm with strong winds hitting the building at a certain angle would cause the building to collapse. A storm with these conditions would hit once every 16 years. This is the story of how it all unfolded, how they took care of the problem, kept it out of the media, and more.

Randomly, this happens to be where Apple has a marketing and sales office.
