I think you may be onto something Baron... just a few questions - how do you set the city section of the stage alight without setting the whole stadium into a burning inferno? The stage looked to be on scaffolding, perhaps a metal surface...
also where are the athletes in this scenario? in the lower section next to the burning city surface? In most summer games ceremonies, once they get the athletes in, the athletes normally take up the entire center section and leave the running track for the torch to run around. So if the athletes are in the lower section, I am not sure how they will get the torch to do a lap around the stadium before they unveil the cauldron lighting. Interested in your thoughts!
(the paper that the athletes walked over in Beijing was a nice touch, wonder where that is now..)
