A failure of RA channel 1 made the a/c go to power flight idle.
The crew was in IMC conditions, so heads were inside looking at the nice pictures in front of them. Read and interpret. Yet the a/c stalled ...
No corrective crew action taken ...
as per Dutch "NTSB" report
So what is your conclusion ?
TRE captain copilot and third crew member on jumpseat were doing what ?
What did the CVR say, were they talking, sterile environment below 10000ft etc. ???
In the questions after, the Chief investigator specifically mentioned no avoidance actions were on tape or shown on FDR to validate rumors the crew made evasive actions to not "hit" anything.
They were just along for the ride, pretty much for the whole flight after AP engagement.
