According to the Associated Press, the latest theory was that USAir
427 may have crashed due to wake turbulence from a Delta 727 4.1
miles in front of the 737, perhaps causing a vortex in the vicinity
of US 427.

4.1 miles exceeds the 3 mile limit imposed by the FAA.  However USAir 427
was at 5600 ft while DL 1083 was at 5900 ft.  The FAA requires planes
to be at least 1000 ft vertically from each other.

DL 1083 was a flight from Toronto to Pittsburgh.


How many mathematicians does it take to screw in a lightbulb?
One; who gives it to 6 Californians, thereby reducing it to an earlier riddle.
