calvin and hobbs show you what caitlin is speaking about plus there's video;

Russia has declassified the video footage of the largest nuclear explosion of all time, the Arctic detonation of the so-called “Tsar Bomba” in 1961.

The explosion was 1,500 times more powerful than those which destroyed Hiroshima and Nagasaki combined, and ten times more powerful than all munitions detonated during the entirety of World War Two. Its mushroom cloud was 42 miles high, over seven times the height of Mount Everest. It was 59 miles wide. It yielded 50 megatons, but could have been rigged to yield twice as much with technology that was available at the time.

The footage is a sight to behold, and serves as a sobering reminder that not only have we been living on the same planet as these horrible things for many generations, but the only reason any of us are still around is by sheer dumb luck. We’ve come inches away from total nuclear war not once, not twice, but many times during the last cold war due to miscommunications and technical malfunctions, which could have easily gone the other way if things had been just a tiny bit different.....read and watch more......
