Unfortunately, the atmosphere doesn’t
always give obvious clues that it’s cooking
up potentially deadly winds. This can affect
experienced airline flight crews as well as a
student who’s had only a couple of flying lessons. Now and then, what looks like a harmless
rainshower can prove deadly to an experienced
crew and its passengers on a large airliner.
A tragic example is the August 2, 1985, crash
of Delta Air Lines Flight 191, a Lockheed L-1011
TriStar at the Dallas-Fort Worth International

Airport that killed eight of the 11 crewmembers, 126 of the 152 passengers, and one person
on the ground.
CLOUDS CAN HIDE VIOLENCE. Five seconds of
the National Transportation Safety Board’s transcript from the cockpit area microphone (CAM)
during the two minutes before the flight crashed
reveals the Delta pilots saw what we now know
was a clue to possible trouble—but neither the
pilots nor controllers recognized it.

ost of the time, the weather gives a sign that it’s brewing trouble.
You don’t have to know much meteorology when you show up at
the airport for a scheduled flight to find a thunderstorm’s winds
rocking the tied-down airplanes. No question, you’ll have to wait
until later to go flying. A forecast for poor visibility on a planned route of flight
tells you to stay on the ground unless you have an instrument rating.
