The U.S.A.F. Airborne Laser aircraft sits on the tarmac at Andrews Air Force Base outside in 2007. The modified 747 aircraft used a high-energy Chemical Oxygen Iodine Laser to generate an energy beam from the aircraft's nose to intercept and destroy a hostile ballistic missile during the boost phase of its trajectory. On Feb. 11, 2010, the flying test bed destroyed a ballistic missile off the coast of Southern California. The program was canceled in 2011, and in 2012, YAL-1 was flown to the U.S. Air Force “bone yard” near Pima, Ariz., to be scrapped.
