glass reference help

Hey all,
I'm from a major movie visual effects company, Industrial Light and Magic, a division of Lucasfilm, and am currently in the process of looking for video reference of glass "buckling". Like if a bomb went off inside a building it would create a suction, which would pull the glass windows in a little bit before it exploded outward. We're trying to find instances of that type of glass warping/buckling, either from stress tests or actual explosions, it doesn't really matter. We're just trying to see what the glass looks like when it's bending. If you have any information on where I might be able to find video clips of this happening, either downloadable on the internet or on a dvd or a video, or direct me to someone that might know, it would be much appreciated.

Thank you for your time and help,
Luke
