Firefighting technique

14 min long video of firetrucks trying to put out the fire of the Asiana AFTER
everyone got out.

Comments there are NOT highly complementary of the SFO
firefighters.

Anyone here care to comment?
Educated guess, but I'm thinking the fire was being fed by the passenger oxygen units. The pictures of the interior post crash show most if not all of the oxygen masks deployed - either there was a crash-induced short that deployed the masks, or the vertical g-forces overcame the restraints - my money being on the later. If even a few of those activated, they would be dumping lots of oxygen into the fire. As the Apollo 1 tragedy demonstrated, in an oxygen rich environment, fire resistant and even some normally fire-proof materials burn quite well. Worse, once one of those oxygen units starts burning, they provide their own oxygen and are close to impossible to extinguish (see ValuJet Everglades cargo fire and crash). Get a couple of those burning, chain reaction to nearby units, and you'll have a heck of a fire that can't be extinguished using normal methods.

Sort of what appears to have happened to Asiana...
