Looking for a transcript of the NTSB statement at the press conference around 4:30 PDT today, but here are a few data points I recall (subject to my faulty memory; if anyone can find a link or remembers better, please do correct me):
Voice recordings for the 2 hours prior to impact revealed no discussion or other indicator of mechanical problems.
After being cleared for landing, the crew voiced a target final approach speed. [I forget the number... maybe 142 knots?]
At 7 seconds before impact, voice recordings include a crew request for more power.
6 seconds before impact, the pilot added power.
3 seconds before impact, the stick shaker engaged, indicating imminent stall.
1.5 seconds before impact, voice recordings include a crew request for a go-around.
This was all what the NTSB calls an "audition" (preliminary review) of the voice recordings.
The flight data recorder included data from the entire 24-hour period before the impact; thus, the whole flight.
Preliminary review indicated no evidence of any mechanical problem.
Engine output was normal.
And this was in an answer to one of the questions from reporters present:
On final approach, the approach speed was substantially below the voiced target final approach speed -- not just a few knots below.
Anyone have other recollections of the data shared, or a transcript?
