Obviously taking over the controls and crashing a flyable aircraft is not in Southwest SOP's
So, since we have no extenuating circumstances to justify crashing an aircraft then Southwest has no other choice.
The lawyers who represent the 15 people who were injured would absolutely be having an orgasm, buying yachts, and vacation homes if Southwest had not taken action as it would indicate that crashing an aircraft is their policy since there appears no extenuating circumstances at this point.
