"The drama of a 2x4 shot from an air cannon at glass windows"

Architectural testing concern HTL will be at GlassBuild America shooting missiles at windows again. The demonstration/demolition follows the Miami-Dade large missile protocol by shooting 2x4s at impact-resistant and non-impact-resistant windows. A press release from HTL quotes NGA Industry Events Director Susan Jacob: "There is nothing quite like the drama of a 2x4 missile shot from an air cannon at glass windows." Wish I was going! I checked HTL's website for some footage, but was left wanting. There's a link for client videos (and there's some top name clients in there), but they all seem to be password-protected. So it was off to YouTube to find this:

Another interesting short video — less than two minutes — was shot at last year's Glassbuild conference; a reporter from e-Glass Weekly played word-association with a few exhibitors. If this small sampling is any indication, the fenestration industry does not like the NFRC at all; was optimistic (as of last year) about commercial construction; and thinks green building and LEED are the future.
