I think the crew did exactly the right thing regarding the casualty - there was no doubt he needed to go to hospital quickly but his injuries seemed limb threatening rather than absolutely life threatening. So with the world watching they made sure that on tape they were seen asking the paramedics the question and receiving the answer that 'Yes he will die if he doesn't go in the helicopter' whether that was strictly true or not. Spot on it's just a shame that the rules don't seem to allow a certain amount of discretion in these matters.
As for the helmet business I'd love to see what the manufacturers have to say about the 'serviceability test! And why did it suddenly not fit after all the flying he had done that day (probably more editing to cram several day's ops into one 'busy shift'.
