This video shows the effect of the high-energy laser beam from the Boeing Advanced Tactical Laser (ATL), fired at a stationary truck from a US Air Force NC-130H (Hercules) flying over White Sands Missile Range, New Mexico, on August 30, 2009. The ATL is a chemical oxygen iodine laser (COIL), and is a scaled-down version of the megawatt-class high-energy laser in the Boeing YAL-1 Airborne Laser (ABL).
Did that say scaled down? Because this thing was powerful enough to set a truck's hood on fire from who knows how far away. Now imagine the much more powerful megawatt laser pointed at your face. You'll have to wear glasses after that for sure!
Thanks to Zach, who has one of these lasers mounted on his arm to heat frozen burritos. Good lookin', Zach, love those things.
