Folks, those two pilots may well be reading this forum from time to time so I'm not sure automatic condemnation is appropriate. Can we wait for an investigation to run its course, please?
You have got to be kidding me. This has made international news, it is shamefull and deserves every prod or any speculation. Situational awareness lost as a result in a disagreement over company policy is simply the best explanation I SPECULATE those guys could come up with. The only argument up there was probably over what defense they could agree to on their way back.
Also understanding the CVR records only the last 30 minutes of flight, they may have thoghtfully planned their cover up to strech out 30 minutes they spent spooning in the cockpit to plan a return performance.
