xcitation, I probably should have said "could" instead of "would", my bad. You had stated that SOP was not to put them on. I was amplifying your answer with the question when could the passengers have put them on given the suspected extreme turbulence would severely bounce any passengers who unbuckled seat belts to start putting one on.
You stated it was SOP not to. I intended to append that it very probably was not physically possible. My wording got sloppy. Please excuse me.
