The atomic fireball sears the desert with flame and boils upward just before break ing clear. The 300-foot steel tower that held the "nuclear de vice" vaporized in the first split second of fission's heat. Rockets fired eight sec onds before the blast leave vertical parallel smoke trails. Their bend in out rushing blast gives scien tists photographic evidence of concussion pressures. This picture was made from News Nob, seven miles from the blast center.
