Transparisteel, almost.

The Air Force is testing transparent aluminum… As Karen Traviss points out, we’re getting damn close to transparisteel!

Also, the testing is at the Wright-Patterson Air Force base… I’ve been there. It’s where the National Museum of the U.S. Air Force is. Totally a must-see for anyone into that sort of thing – it’s huge. (And if you’re lucky, sometimes they give tours of the warehouses of all the stuff they’re not putting up in the main museum. Or at least they did a few years back.)
