"The reason we do not crash as many aircraft is because our understanding of material science and our maintenance and servicing techniques have improved drastically. NDT and environmental health monitoring systems mean that these days the engineers can do a better job for us than ever in the history of aviation."
Really - you need to get out to DASC/AAIB and such places and find out why we crash our planes. Agreed we crash less today than we did in the 1940's and 50's but that is as much about safety awareness training as it is mechanical/engineering improvements.
80% of crashs are still attributable to the carbon base unit having a bad day - yep the human sat in the cockpit having a momentary lapse or whatever else you like to call it.
