EXCERPT: [...] Tsar Bomba was no ordinary nuclear bomb. It was the result of a feverish attempt by the USSR’s scientists to create the most powerful nuclear weapon yet, spurred on by Premier Nikita Khruschchev’s desire to make the world tremble at the might of Soviet technology. It was more than a metal monstrosity too big to fit inside even the largest aircraft – it was a city destroyer, a weapon of last resort.
[...] In order to give the two planes a chance to survive – and this was calculated as no more than a 50% chance – Tsar Bomba was deployed by a giant parachute weighing nearly a tonne. The bomb would slowly drift down to a predetermined height – 13,000ft (3,940m) – and then detonate. By then, the two bombers would be nearly 50km (30 miles) away. It should be far enough away for them to survive.
[...] the bomb created a fireball five miles wide. [...] The flash could be seen from 1,000km (630 miles) away. The bomb’s mushroom cloud soared to 64km (40 miles) high, with its cap spreading outwards until it stretched nearly 100km (63 miles) from end to end. It must have been, from a very far distance perhaps, an awe-inspiring sight.
On Novaya Zemlya, the effects were catastrophic. In the village of Severny, some 55km (34 miles) from Ground Zero, all houses were completely destroyed (this is the equivalent to Gatwick airport being destroyed by a bomb that had fallen on Central London). In Soviet districts hundreds of miles from the blast zone, damage of all kinds – houses collapsing, roofs falling in, damage to doors, windows shattering – were reported. Radio communications were disrupted for more than an hour. [...] 10 times more powerful than all the munitions expended during World War Two...
