The biggest bomb of the time of World War II exploded underwater when marine divers tried to defuse it in Poland. For safety, more than 750 people had to be evacuated from the site.
This is the Tallboy bomb that was dropped by the British Army during World War II in an attack on a German cruiser. It was about six metres long, weighed nearly 5,400 kilos, including 2,400 kilos of explosive, and exploded as they tried to defuse it in the Piast Canal.
In the video posted by Reuters, it can be seen that the explosion was so powerful that the birds flew away in fear, but fortunately, no one was injured.
“The deflagration process has turned into a detonation. The target can be considered neutralized, as it will no longer pose a threat to the navigation channel,” spokesman for the 8th coastal defense fleet Grzegorz Lewandowski told local media.
The initial plan was to defuse Tallboy with a process of burning the explosive charge at lower temperatures, but Polish Navy officers were aware that this method could fail and the bomb could explode during the attempt.
