Now I *KNOW* the sky is falling

Qantas Air, long famous for its utterly unblemished safety record - even remarked upon by Dustin Hoffman's savant in Rainman - has had four incidents in the last 90 days including one this morning. El Al has an equally amazing record but the assumption is that Israeli security explains much of their success. Qantas was simply far and away the cream of the crop with unassailably top-notch with materials and maintenance. What can one do but conclude that up is now down and red is now green and day is now night?
