Looks like I'll have to double-check credibility of my
references or consult them with more care;)
Indeed,offical reports on the incidentss rejected
lightning to be the cause (becouse no evidences of
in-flight fire,explosion,or lightning strike were"
The "black box" flight recorders showed unmistakable evidence of a
typical microburst incident as the cause of the accident. Approaching
the field there is a headwind and updraft as the plane enters the edge
of the downwash; typical pilot reaction would be to nose down and reduce
power. Unfortunately, immediately after there is a tailwind and
downdraft and the crew is often unable to recover before hitting the
ground. New avoidance procedures involve keeping power on and flying
constant attitude.
