I was reading this article earlier today. Pretty cool stuff.
Wright-Patterson is about 15-20 minutes from the house I grew
up in. It's the home of Hangar 18—where the Aliens from the
Roswell crash were supposedly held. Anyway, this is pretty cool.

10/17/2005 - WRIGHT-PATTERSON AIR FORCE BASE, Ohio (AFPN) -- Engineers
here are testing a new kind of transparent armor -- stronger and
lighter than traditional materials -- that could stop armor-piercing
weapons from penetrating vehicle windows.
The Air Force
Research Laboratory's materials and manufacturing directorate is
testing aluminum oxynitride -- ALONtm -- as a replacement for the
traditional multi-layered glass transparencies now used in existing
ground and air armored vehicles.
The test is being done in
conjunction with the Army Research Laboratory at Aberdeen Proving
Grounds, Md., and University of Dayton Research Institute, Ohio.
ALONtm
is a ceramic compound with a high compressive strength and durability.
When polished, it is the premier transparent armor for use in armored
vehicles, said. 1st Lt. Joseph La Monica, transparent armor
sub-direction lead
"The substance itself is light years ahead of glass," he said, adding that it offers "higher performance and lighter weight."
Traditional
transparent armor is thick layers of bonded glass. The new armor
combines the transparent ALONtm piece as a strike plate, a middle
section of glass and a polymer backing. Each layer is visibly thinner
than the traditional layers.
ALONtm is virtually scratch
resistant, offers substantial impact resistance, and provides better
durability and protection against armor piercing threats, at roughly
half the weight and half the thickness of traditional glass transparent
armor, said the lieutenant.
