The normal hazards of weather are plenty enough to deal with in
the aviation biz... but sometimes the natural foes we face pale in
comparison to some of the 'unnatural' ones. A T-18 SportPlane (file
photo, below) found this out the hard way, getting caught in the
rotorwash of a passing helo and paid the price for it's unfortunate
proximity. So... in addition to all the natural hazards we face,
please keep an eye out, ALSO, for the man-made "Gotchas" that may
occasionally creep up and catch you unawares.
