White Sands Blast Test Rattles 100-Mile Area

WHITE SANDS MISSLE RANGE - The largest non-nuclear high explosive ever set off in the free world sent dust clouds rolling 15,000 feet into the air over this U.S. Army test facility shortly after noon Thursday.

The shock wave resulting from the 4,800 tons of ammonium nitrate and fuel oil that filled in for an 8-kiloton nuclear bomb shattered windows and knocked Venetian blinds from their brackets at a complex of mobile offices about three miles from ground zero of Minor Scale, the third in a series of high explosive test blasts put on by the Defense Nuclear Agency here.

The blast was heard in communities as far away as Las Cruses, more than 100 miles southwest and across the San Andres Mountains.
