The sound of the window breaking and the sight of his alarmed face is priceless; what did he think was going to happen?

Remember that dizzying, quarter-mile-high glass observation deck that opened on the 103rd story of Chicago's Sears Tower recently? Well, the New York Times now has an interesting article about the science of making the damn thing work without killing anyone.

From the mailbag: "One or more of the giant glass windows apparently fell off the side of the NY Times building. There are fire trucks everywhere along 40th Street."
