I find all of this talk about following or not following SOP's really worrying.
EFATO is not SOP's, its how the aircraft is certified, by not following it you are entering no mans land. Sure the aircaft can be flown with 90 degrees of bank or even inverted (Tex Johnson did it on a 707 and nearly got fired).
You are playing with peoples lives and should take that seriously, if you want to be a test pilot, do it without pax and over the sea (as long as I am not fishing there).
There are no if's and but's about EFATO, if you dont understand it ask someone to teach you.
