Oh my word, the idiocy gets worse! Someone trying to pretend that he has seen an 'incident', bank being judged from a view out of the cabin.....whatever next?
IF there was an airprox, it will be official. You cannot, even as a fairly experienced pilot, accurately estimate bank from a cabin window unless you have an across horizon reference. It's not unknown for turboprops to bank more than jets due to their slower speed and hence less 'g', but still naughty- but I defy anybody to put a figure to it!
End of 'incident'?
