You guys hit the nail on the head! Moving throttles are just great ..... Because they move forward when thrust increases. When not, no thrust!
Now if a thrust increase is anticipated or desired and they do not move, what on earth could be the reason?
- malfunction (already discarded by NRSB)
- bad/insufficient training?
- old AB habits?
- bad monitoring of crew for whatever reason?
To conclude: amen again to Schnowzer
