Possibly in the pilots cameras that looked too dangerous to evac on the left side. Dont hang them from your armchair without all of the facts, is all I say.
So, there's a known fire on the right side and possibly a fire on the left side. Yep, I think we'd all agree that no evacuation was a great decision.
If you can read the QRH by the glow of the fire, perhaps it's time to get out!
