No Fly Zone Declared in Japan

"It is very clear that we are at a level six, which is an intermediate level between what happened at Three Mile Island and Chernobyl," ASN president Andre-Claude Lacoste told a news conference in Paris. "We are clearly in a catastrophe."
On Three Mile Island, the radiation leak was held inside the containment shell — thick concrete armor around the reactor. The Chernobyl reactor had no shell and was also operational when the disaster struck. The Japanese reactors automatically shut down when the quake hit.
The International Atomic Energy Agency (IAEA) imposed a 30-km (18-mile) no-fly zone around the Fukushima site Tuesday. msnbc
