2.8 million tons of bombs were dropped on Germany by the Allies during World War 2. Researchers think that about 5% of those failed to explode upon hitting the ground, and even today we routinely discover them buried underground. In Munich this week, a 550-pound unexploded bomb was found beneath the Schwabinger 7 nightclub, a famous hangout of the Rolling Stones in the 1970s.
The decaying bomb, one of the estimated 50,000 dropped on Munich during the war, was found rusting and buried underground. Diethard Posorski on the construction team who found the bomb said: ‘That is a chemical delayed-action detonator. I am not defusing that – I’m not suicidal.’
Around 2,500 people within a 1,000 mile radius were evacuated from their homes as a precaution for the bombs detonation, which was carried out at night and looks beautiful. (See above.)
Trigger mechanisms on undiscovered bombs are increasingly wearing away as time goes on, which means that they may explode unexpectedly at some point in the future.
