Submission + - North Korea Detonates First Hydrogen Bomb

An anonymous reader writes: HughPickens.com writes

The NYT reports that North Korea has announced it has detonated its first hydrogen bomb dramatically escalating the nuclear challenge from one of the world’s most isolated and dangerous states. “This is the self-defensive measure we have to take to defend our right to live in the face of the nuclear threats and blackmail by the United States and to guarantee the security of the Korean Peninsula,” said a female North Korean announcer on the state-run network. “With this hydrogen bomb test, we have joined the major nuclear powers." The North’s announcement came about an hour after detection devices around the world had picked up a 5.1 seismic event that South Korea said was 30 miles from the Punggye-ri site where the North has conducted nuclear tests in the past.

“North Korea’s fourth test — in the context of repeated statements by U.S., Chinese, and South Korean leaders — throws down the gauntlet to the international community to go beyond paper resolutions and find a way to impose real costs on North Korea for pursuing this course of action,” says Scott Snyder, a Korea expert at the Council on Foreign Relations. According to the Times, the test is bound to figure in the American presidential campaign, where several candidates have already cited the North’s nuclear experimentation as evidence of American weakness — though they have not prescribed alternative strategies for choking off the program. The United States did not develop its first thermonuclear weapons — commonly known as hydrogen bombs — until 1952, seven years after the first and only use of nuclear weapons in wartime.

Submission + - Software Bug Halts F-22 Flight

mgh02114 writes: The new US stealth fighter, the F-22 Raptor, was deployed for the first time to Asia earlier this month. The first flight from Hawaii to Japan was forced to turn back when a software glitch crashed the F-22 on-board computers as they crossed the international date line. The delay in arrival in Japan was previously reported here and here, with rumors of problems with the software. CNN television, however, this morning reported that all every fighter completely lost all navigation and communications when they crossed the international date line. They reportedly had to turn around and follow their tankers by visual contact back to Hawaii. According to the CNN story, if they had not been with their tankers, or the weather had been bad, this would have been serious. CNN has not put up anything on their website yet. This follows previous reports that a software bug in the F-16, caught in simulation before the plane ever flew, that would have caused the fighter to flip upside down when flying over the equator.
