...accident investigation culture that looks for problems then fixes them. The recent record in the U.S. has been especially noteworthy. Airlines and the Federal Aviation Administration (FAA) oversight office, led by Associate Administrator Nicholas Sabatini, have made history in the past three years: the .017 accident rate per 100,000 takeoffs has made the U.S. the safest system ever...
