This reminds of the Hancock tower case in Boston. Shortly after completion, the windows started popping off en mass. An investigation was carried out to figure why. Hancock tower was one of the first towers to have an all glass curtain wall. AS such, the engineers who designed had very little experience with the kind of glazing required for the very large panels of glass in tiny mullions. It turned out that the glass right next to the soldering wasn't strong enough.

However, the investigation into why the windows were falling off also revealed that the tower had insufficient wind bracing!

Edit:And apparently I didn't fully read the first post.
