I've been fascinated by the events in Japan and have spent almost all day watching the various clips coming out of there.
When I first saw this clip I wondered what the hell I was seeing, now I find out I am not the only one that noticed it!

As we accurately reported earlier today, the explosion at the Fukushima nuclear plant in Japan was the result of a nuclear meltdown of the reactor core at the facility.
The Nuclear and Industrial Safety Agency (NISA) confirmed the meltdown  Saturday afternoon. Fukushima is one of the 25 largest nuclear power stations in the world. The NISA is affiliated with the Ministry of Economy, Trade and Industry.
High levels of cesium and iodine, by-products of nuclear fission, are being reported and providing more evidence that a nuclear meltdown is currently underway.
It is now certain Japan is experiencing a Chernobyl event. “At this point, events in Japan bear many similarities to the 1986 Chernobyl disaster. Reports indicate that up to 1.5 meters (4.9 feet) of the reactor fuel was exposed. The reactor fuel appears to have at least partially melted, and the subsequent explosion has shattered the walls and roof of the containment vessel – and likely the remaining useful parts of the control and coolant systems,” Stratfor explains .
“Given the large quantity of irradiated nuclear fuel in the pool, the radioactivity release could be worse than the Chernobyl nuclear reactor catastrophe of 25 years ago,” said Kevin Camps , a nuclear waste specialist.
Prior to the explosion of the containment structure, exposure rates outside the plant were at about 620 millirems per hour . Radiation exposure for the average individual is 620 millirems per year. Virtually any increase in ambient radiation can raise long-term cancer rates, and authorities distributed iodine, which helps protect against thyroid cancer, The Oregonian  reports.
As the image above illustrates, the prevailing jet stream  moves from Japan to the United States across the Pacific Ocean. Airborne radiation would work its way into the jet stream and reach the United States in less than 36 hours. Jet streams flow from west to east in the upper portion of the troposphere.
By downplaying this serious disaster, the Japanese government is not only endangering its own people, but also millions of people in the United States and Canada.
The cover-up by the Japanese government provides more evidence that government cannot be trusted to safeguard the lives of its citizens.
