Regarding the 999 calls, or lack thereof, to be fair to the people who witnessed this horrific accident they probably had no idea what to do. Put yourself in their situation, you dont really know what happened, what is happening, and if the emergency services have already been called, and as for Towers themselves, at first it really seems shocking that it took 20 minutes to call 999, but wasnt it mentioned that Alton's own First Aiders on the scene? Maybe it was a case of "How bad is it? Very bad. Okay, let's call 999."
