And One Penn Plaza is another with a mostly glass skin, although I think the mullions are a little larger than on the John Hancock. And it went up around the same time, opened in 1972. In the Hancock's case, its structural flaws were corrected with additional bracing and a tuned mass damper.

I wonder how much One Penn moves around in a good windstorm? Too bad nobody here works on its upper floors
