It's just that the fire would have to burn all the communication before being reported which seems very unlikely unless there's a spot where all the radios are. In Swissair 111 they reported the fire 10 minutes before losing communications (12 mintes before the radar lost them) and the captain was heard getting out of the seat by the ATC indicating he was fighting the flames.
There must be a serious flaw for it to spread so quickly the plane just disappears.
I've heard that in some serious situations the crew may turn it all off to conserve power. As unlikely as it is, maybe they were hit with a double whammy of power problems and fire?
