The U.S. Army has destroyed about 90 percent of its aging chemical weapons, from the desert chemical depot.
Wednesday just after 2 p.m. the last of the hard weapons were burned in a 1,500 degree furnace. A tray of 23 projectiles came out of the furnace at 2:11 p.m.
At its peak, the desert chemical depot held some 13,600 tons of chemical agents, making it the world's largest.
The entire project will be complete by the weekend when the depot will incinerate bulk supplies of Lewisite, a powerful skin, eye and lung irritant.
