So far, NTSB says the data stopped 2 seconds after..... But is this just the video? Can't imagine the flight data recorders stopped.
That sure makes the case for keeping video out of the cockpit ... experimental as well as commercial.
IMHO, I cannot for the life of me understand why video (for the purpose of incident investigation) is not on all commercial aircrafts.
In lack of better, ANY video system is better than none.
