Just to put a little balance into this debate...
remember; it's a 'crew' awareness thing, this 500' stable gate.
I'm not it any way admonishing responsibility of the crew for spotting an ommision at 500' (which besides the way was 15kts fast), but ask yourself why no ASR was filed? - could it be because on 5th censec early neither pilot due to extranneous factors actually noticed?
Now, not to finger anybody, but why would the F/O now be firmly entrenched as a captain with EJ, and the captain himself be summarily sacked? No disrespect to F/O involved, (a thoroughly professional chap with the upmost integrity), but perhaps just a teeny bit of company personal retribution against a forthright individual who has stood up to EJ in the past?
It's not nice to see fellow professionals go down no matter what the circumstances. It could happen to any of us.
