On the 13th of May, 2000, residents in the Dutch city of Enschede noticed smoke in the sky. A small industrial complex in the northern part of the city was on fire. Fire engines made their way towards the blaze, while people watched from a safe distance, fully expecting to see it brought under control within a few hours. Instead, at around 3:30pm, a massive explosion shook the entire city, obliterating an entire neighbourhood in a matter of moments.
