Blame
Can everyone stop 'blaming' and apportioning 'responsiblity'. You really are making me sick. It's bad enough that this happened, but to be launching in with fatuous crap about blame........????
Fine, discuss possible 'scenarios', offer 'opinions' etc. Without the facts you are just talking crap. How does anyone yet KNOW that the Russians had received a climb RA? Never heard of TCAS giving conflicting RA's? If the DHL crew had received a TA, where was their situational awareness- not asking for the traffic/ aware the traffic was not responding to descent instruction/knowing the traffic was instructed to descend but blindly following RA to disaster? You can blame the cleaner if you try.
The discussion about TCAS is very important. I have come to realise that it is a double-edged sword: you guys out there relying on it are headed for a fall. And I am not just talking about mis-identifying traffic, either.
