WHILE TURNING, HE LOST SIGHT OF THE ARPT, THEN ROLLED OUT ON THE WRONG HEADING & STARTED FLYING TOWARD A STROBE LIGHT AT AN INDUSTRIAL COMPLEX.

AN EXAM OF THE ENGS & FUEL PUMPS REVEALED NO INDCN OF A PREIMPACT FAILURE. NO PHYSICAL EVIDENCE OF A LIGHTNING STRIKE WAS FOUND, BUT THE NOSE & ENGS WERE BADLY DAMAGED FROM IMPACT.
