Potentially fatal flaws in designs of buildings

[Vertigo58]

Some or most of you may recall the PBS series on Building Big.

There was a good story on this particular skyscraper in NYC.

It seems the skyscraper's bolted joints were too weak to withstand 70-mile-per-hour wind gusts. It was just mind boggling to see how such an important feature was overlooked but later corrected.

It would be great if they reran this program/subject. It was very interesting. Now available on DVD.
