Operation Dominic - Sunset (1962)

The Soviet Union had abrogated the 34 month old de facto nuclear testing moratorium on 1 September 1961 by initiating an unprecedented series of atmospheric nuclear tests. The initial U.S. response was to commence its own test series (Operation Nougat) two weeks later. Nougat was an underground series however, restricted to very low yield devices.

Numerous atmospheric tests, many at high yield, were of course on the drawing board at the weapons labs, some carried over from planning for previous test series. The Dominic Sunset test successfully reached the full design yield with a yield-to-weight ratio of 4.06 kt/kg. The vapor cloud rose to over 60,000 feet.

Nuclear detonations produced high above the ground do not create mushroom clouds. The heads of the clouds themselves consist of highly radioactive particles, primarily the fission products, and are usually dispersed by the wind, though weather patterns (especially rain) can produce problematic nuclear fallout.

Nuclear explosions are often accompanied by short-lived vapor clouds known variously as “Wilson clouds”, condensation clouds, or vapor rings. The low pressure region causes a sharp drop in temperature, causing moisture in the air to condense in a shell surrounding the explosion. When the pressure and temperature return to normal, the Wilson cloud dissipates.

Saudi Arabia moves to allow girls to play sports in school

Saudi Arabian authorities have been asked to consider lifting a nationwide ban on sports for girls in schools, according to the official SPA news agency, in a religiously conservative country that included women in its Olympic team for the first time only two years ago.

Under a strict interpretation of Sharia, or Islamic law, Saudi women are banned from driving and must gain formal permission from a male relative to leave the country, start a job or open a bank account. But King Abdullah is pushing cautious social reforms on women’s rights in the face of conservative resistance.

"I'm just reminding you," Bruce snapped. He abruptly sagged, all the fire going out of him at once as he fell into the chair. He rubbed his hands through his hair. "I'm sorry, that... that wasn't very nice of me."

SPIT IT OUT!

"I’m not guilty!"

"You're not as funny as you think you are," Bruce grumbled, tugging the pants on. "I'm starving. Someone, please, make me food. Are the witches all dead? They better be."

"Are you sure this is legal?"

"If not I know a couple of brilliant lawyers that would be more than willing to help us out." Andie shrugged, looking over at him. "Don’t worry so much."
