@Lonewolf_50:
"Causes and effects aside, and mitigation, the NTSB has been releasing a lot more info a lot faster than I am used to seeing after a fatal accident."
Well, they had immediate access to the crash site, quick recovery of the voice and data recorders, and the flight crew all survived relatively unharmed to interview. Given the circumstances, I don't think the info release is surprising.
It might also have something to do with the compressed media atmosphere that exists now, i.e. an attempt to quash unsubstantiated rumors before they spread virally over social media.
