Agree that a 10 min delay to an ambulance being called is very questionable. They might well have been following internal procedures getting Park first aiders there to assess but for goodness sake, people were very seriously injured. Members of the public said that was immediately apparent. sone riders were limp and knocked out. I bet the public bystanders and witnesses feel awful knowing now, in hindsight, that no fucker had called an ambulance and the fire brigade whilst they were all stood there with mobile phones (and some bloody videoing and taking grim pictures). It almost beggars belief. The public thought that AT woud immediately make the call but they didn't. It just goes to show, if you see a serious accident don't trust anyone to react quickly, do it yourself.
