Fans of the British comedy troupe
Monty Python share a particular fondness for the character of Ron Obvious, the
first man ever to try to jump the English Channel.
“How far
is it across the Channel?” asks an interviewer (John Cleese).
“Oh, about
21 miles from Dover to Calais,” replies Mr. Obvious (Terry Jones).
“And
what’s the farthest you’ve managed to jump in practice?”
“A little
over six feet.”
Sure
enough, the record jump attempt proves … anticlimactic!
The sketch
provided a particularly sly reminder that willpower and optimism come out
second best when they take on the laws of physics.
In general
aviation, this is proven the hard way year after year by a tiny minority of
aviators who feel that an immediate need to complete the flight outweighs the
very real risk that they won’t. Making the attempt in the face of known mechanical problems, hazardous weather, or simple inexperience can
vastly increase the cost of not reaching that destination.
Consider
the following accident report and decide what you would/would not have done ……
The Cessna
stopped for fuel at Columbia,
Missouri on the way from Jackson, Tennessee to Sioux City, Iowa.
It took on 26 gallons. While on the ground, its pilot called to get a weather
briefing for the final leg. The briefer advised that Sioux City was IFR and
expected to remain so. Low clouds covered
much of the route, including northern Missouri and western Iowa, with tops
reported between 2,500 and 4,500 feet. Weather in eastern Nebraska was
“beautiful,” but instrument conditions also were expected to develop
there around his ETA; temperature/dew point spreads were already narrow and decreasing. The pilot responded that his job and
vehicle were in Sioux City, so the briefer identified Wayne, Nebraska,
28 nautical miles west-southwest, as the nearest airport
reporting clear conditions.
They
discussed the option of flying VFR over the cloud deck, but because the pilot was not instrument rated, the briefer suggested flying northwest to Kansas City, then turning
north on the west side of the Missouri River. He also recommending stopping at
Omaha to reassess the situation. The pilot replied that he’d decided to fly direct to
Sioux City above the clouds, diverting to Wayne if conditions required. The briefer advised him to get weather updates en-route and provided
him with a list of the appropriate frequencies.
The Cessna
took off at 3:40 p.m., an hour and a half before sunset. The moon
had gone down in mid-afternoon. The pilot requested and received flight
following. Around 6:30 he reported clear skies and good visibility above the
clouds to the Sioux City approach controller. The controller asked him to “let
me know when you get ground contact” and advised that Sioux City was under a 700-foot
overcast. Wayne and Norfolk, Nebraska,
still reported clear skies. The pilot responded that he was beginning his
descent without ground contact, adding “I’m sure I’m getting fairly close,” and
said he planned to land on Runway 36 at Wayne.
Descending
through 2,000 feet, less than 600 feet above ground level, he still could not see the ground. The controller provided an updated observation from 10 minutes earlier
that included a 200-foot scattered layer at Wayne. The
pilot continued to descend, reporting negative ground contact at 1,800 feet.
Acknowledgement of the loss of radar contact was the last transmission received
from him.
The
wreckage was found in a small area at the end of a short debris path,
suggesting a steep angle of impact. The next METAR from Wayne, six minutes after the accident, listed the ceiling as overcast at 200 feet. Norfolk, another 25nm southwest, stayed clear with good
visibility for two more hours.
FLY SAFE!
