CVR - no alarms after the explosion?
After the ISIS video shows the explosion, the aircraft continues flying for an additional 15 seconds before the video ends with the fuselage relatively still in one piece.
According to the authorities, the CVR records a loud noise of some sort and then nothing. No aural warnings or alarms after that. The CVR is powered from the essential bus so shouldn't we expect alarms and bells after the explosion if that video is real.
