I've just read the CVR transcript as posted in the link above.
I am impressed that this crew was quite professional and sounded (with regard to translation) as any professional pilots might sound.
Note that the captain asked to inhibit the glide slope and flew one dot low...a wise move on a short wet runway...I think they knew what they were doing at that airport. they were acting as any of us might have.
they discussed the reverser situation.
they were cautious about getting a runway report.
they simply sighed at not getting spoilers...this was probably not the first time this happened to them.
but then something went terribly wrong...something that might have been caught with conventional moving throttles...or by simply hand flying and hand throttling on the approach...or something as yet unknown.
I give the benefit of the doubt to the pilots on this one...and hope that we all find out the truth sooner or later.
