First of all, MCAS doesn’t run for 11 seconds - ever.

Wonk,

I guess I should thank you for providing one of the best examples of what happens when you start with a pre-formed conclusion and try to shoehorn the evidence to fit. You have made a...

Except that in a number of cases (at least on the 737) there is no way to silence the alarm. High speed clacker is probably the most annoying one in this category.
