Aviation has proven a quick study on some problems, painfully slow on others. The safety culture that has given us sterile cockpits and relentless emergency drills still hasn't cracked low-wage regional pilots and too-frequent reports of near misses in congested airspace, for instance. And in some parts of the world airline safety remains Plan B (C ... or D ...).
While the past decade's improving commercial airline safety record is very real, we know there will always be a "next big one." The harder we work to be wrong about that, the better.
In the meantime, congratulations to all the folks who work hard every day to make fewer accidents no accident.
