It is a pity I never been there, I was too young to visit London then. I saw just some short documentary that I downloaded from internet. I never heard about a death in there, I heard that the whole corridors in Trocadero were flooded and thus they decided to cancel Alien War rather than repair it. But this may be an official version for media to cover the real reason...
How about the Shock & Awe with Danny Boyle? You wrote that you repaired the audio-video synchronisation already.
