360* X 90* = 32,400 directions that plane could take off on if uncontrolled, beginning at any point along the route after a mechanical malfunction or heart attack.
Now I know the true secret of the JFK assassination: it was a "Coincidence". Someone a mile away was cleaniing his rifle when it went off accidentally, and, darn the bad luck, the bullet hit JFK.
"Accidents happen", right?
Coincidence -- just like the plane that went off the runway last November in Milan. But we've already forgotten that one.
