> I'm certain that were human life so cheap, Pratt and Whitney would have a much shorter dev cycle, too. I read a book recently about the history of Supermarine, and what jumped out was the attrition rate of their test pilots. Ditto for the post-war British jet industry. There is a trade-off point between safety and fast development, but I'm glad we've moved to the side of safety.
