The following was released at 9:30 a.m.:

"The Test Organization has been advised that the blast from this morning's relatively low yield detonation broke at least one window and cracked others in Carson City, Nevada, about 250 air miles from the Nevada Test Site.

"E.K. Butner, an inspector in the Carson City Police Department, telephoned the Test Organization and reported that at 4:50 a.m. PDT, the blast was felt at his home, resulting in a broken window on the side of the house opposite the direction of the test site. He said that several other windows were cracked. He said that he visited neighbors and understood that several windows in other homes had been cracked.

"Representatives of the General Adjustment Bureau, which handles investigation of test damage claims will go to Carson City, probably later today, to try to determine the cause and extent of the damage.

"If the damage is found to be test related, it will be the first from blast waves propagated through the ozonosphere and the first blast damage at any such distance. Ozonosphere blast waves usually are softer than those propagated troposphere.

"Following our forecast trajectories of various segments of the radioactive air mass resulting from the Diablo shot:

"The 10,000 foot level air mass is expected to be centered 10 miles east of the Lincoln Mine at 10:30 a.m., and 80 miles south of Ely at 4:30 p.m.

"The 20,000 foot air mass is expected to be 20 miles east of the Lincoln Mine at 10:30 a.m., and at a point above the Nevada-Utah border 55 miles east of Milford, Utah at 4:30 p.m.

"The 30,000 foot air mass is expected to be 25 miles north of Las Vegas at 10:30 a.m., and 40 miles north of Kingman, Arizona at 4:30 p.m.

"The 40,000 foot air mass is expected to be above the Nevada-Utah border, 30 miles west of St. George, Utah at 10:30 a.m. and 20 miles northeast of Bryce Canyon, Utah at 4:30 p.m.
