The question remains...was it a complete electrical failure? And how far did they fly after getting airbourne with this failure? I think we don't have enough information to make a good judgement call.
If it was a complete electrical failure, they more than likely would have returned to land. But since the original poster says they were in contact with Company I would have to presume they still had battery power or at least a RAT.
I could see completing the necessary checklists and swinging around for landing (after declaring an emergency). Oh...I don't know...maybe 15 - 20 minutes total from wheels up to landing.
Continuing with a failed generator is another story that obviously would allow them to choose the most APPROPRIATE destination.
What actually happened anyone know the details?
I think we always need to think that the only ones who really know what happened are the crew. We shouldn't judge unless we know ALL the details...and even then we should not pass to harsh a judgement.
