tldr for the wikipedia article:
this plane did not crash, it made an emergency landing 2 miles from the airport in an onion field. Only 10 crew and 1 passenger survived. The other 123 souls aboard died of smoke/CO inhalation from the fire.
the sole surviving passenger, 21-year-old Ricardo Trajano, disobeyed the instructions to remain in his seat.
