With all due respect to the Airline Pilots Association, the NTSB are acting as required these days - with information and speculation spilling out all over the Interthingy, not least right here on pprune, the best thing to do is to release as much information as you reasonably can, as fast as you reasonably can.
If the NTSB were to hold back, as in the "good" old days, the media and the public would turn to other, less reputable, sources.
People may not be aware just how much the timescale for information release has become compressed, thanks to "social media" - where, twenty years ago, one had a week, one now has an hour - sometimes thirty minutes.
The journo's phrase for it is "The most important Editor in any newsroom is Phil Space"...
