EOD Bomb Explosive Ordnance Disposal Robot

Another technique is Trepanation, in which a bore is cut into the sidewall of a bomb and the explosive contents are extracted through a combination of steam and acid bath liquification of bomb contents.
Although professional EOD personnel have expert knowledge, skills and equipment, they are not immune to misfortune because of the inherent dangers: in June 2010, construction workers in Göttingen discovered an allied 500 kilogram bomb dating from World War II buried approximately 7 metres below the ground. German EOD experts were notified and attended the scene. Whilst residents living nearby were being evacuated and the EOD personnel were preparing to disarm the bomb, it detonated, killing three of them and injuring 6 others. The dead and injured each had over 20 years of hands-on experience, and had previously rendered safe between 600 and 700 unexploded bombs. The bomb which killed and injured the EOD personnel was of a particularly dangerous type because it was fitted with a delayed-action chemical fuze, which had become highly unstable after over 65 years underground.
