World's BIGGEST & MOST POWERFUL NUCLEAR BOMB explosion of all time! (Cold War Tsar Bomba!)

"This is the single most powerful device ever constructed (and subsequently responsible for the biggest nuclear explosion in history). Known as the Tsar Bomba, this Soviet designed nuclear weapon had a destructive power 10 times the combined force of all conventional explosives used in World War 2, and was 3000 times more powerful than the atomic bomb that destroyed Hiroshima.

Weighing 27 metric tuns, the Tsar Bomba was so heavy it needed a specially modified plane to carry it to the release sight.

And it was on the 30th of October 1961 that the bomb was dropped from an altitude of 6.5 miles above a remote island in the Arctic Ocean.

Because the nuclear device was so absurdly powerful, a parachute was deployed to slow its descent and allow the plane's crew time to escape from the blast.

When the bomb was detonated it released an energy yield equivalent to 50 million tuns of TNT, and created a gigantic fireball that was visible from 500 miles away. The bomb completely destroyed everything within a 22 mile radius and damaged windows in Norway and Finland some thousands of miles away.

Let's hope that such a ridiculously devastating nuclear event will never again take place.

This has been an Amazing Planet production. Thanks very much for watching."
