WITNESSES ON THE GROUND REPORTED THAT THE ENGINES SOUNDED NORMAL WHILE THE AIRPLANE WAS TAXIING TO TAKEOFF. AFTER TAKEOFF WITNESSES REPORTED SEEING WHITE SMOKE TRAILING THE LEFT ENGINE. THE AIRPLANE WAS OBSERVED TO BANK TO THE LEFT WITH A BANK ANGLE OF ABOUT 90 DEG. THE AIRPLANE THEN PITCHED NOSE DOWN, DESCENDED, AND COLLIDED WITH TREES AND THE GROUND.
