Ihave no idea why – I am scared enough of flying as it is – but the other night we all sat down to watch an old episode of Air Crash Investigation on the National Geographic Channel. I don’t watch it because I like seeing people burnt, mutilated or killed in aircraft but because I find it fascinating how they can investigate a heap of burnt wreckage and discover exactly what went wrong. Which part failed or who made the fatal mistake which brought the plane down. The investigators are presented with the tiny bits left over and they can work out exactly what happened. Terrible disasters but fascinating investigations which determine exactly why the plane crashed.
