Only 2 possible sources? AAIB from CVR and would be highly unprofessional so unlikely? Or CP himself, speaking to colleagues, more likely, but even if true the real question is did the Pilot hear him?
We should wait on the facts from CVR and AAIB - hopefully we will get another interim report.
The existence of the call(s) is fact.
Also nobody has mentioned fatigue as a possible factor? I know you guys are strictly limited on flying hours, but crash occurred at end of week and late on a Friday?
It was this crew's only flight of the day so fatigue would have to be cumulative and affect both crew. The same aircraft had flown an almost identical flight earlier in the day.
