And the fuel spilled both away from the fuselage and onto snow, which both kept the main focus of the fire away from people and limited development of the fireball as well. Kerosene (Jet-A) is relatively nonvolatile and tends to burn most violently when dispersed in air. It's not quite as heavy as diesel fuel, in which you can extinguish a lit match, but conditions in this incident probably limited flame development considerably.
