.. the MAX aircraft has 17,000 recordable parameters and Southwest has compiled and analyzed a tremendous amount of data from more than 41,000 flights operated by the 34 MAX aircraft on property, and the data supports Southwest's continued confidence in the airworthiness and safety of the MAX. ... SWAPA also has pushed hard for Angle of Attack (AOA) sensor displays to be put on all our aircraft and those are now being implemented into the fleet. All of these tools, in addition to SWAPA Pilots having the most experience on 737s in the industry, give me no pause that not only are our aircraft safe, but you are the safest 737 operators in the sky.

No, that only means that they believe this will improve pilot's situational awareness. You don't need that feature to override uncommanded trim.

Until the FAA says the aircraft is unsafe, your opinion of these airlines is misplaced. They went beyond what's legally required and added an additional safety feature.

Southwest exclusively flies 737s. They have one of the largest pilot corps for that type. The airline has good safety and maintenance records.

Southwest have been flying since the 1960s, and have I think a total of (3) fatalities. No relation or association to them but the operator and their training matters. Southwest are by any measure one of the safest airlines in the world.

Two lost aircraft. Both new. Both with the same symptoms. Under conditions you would not expect to lose an aircraft.

That's a really really bad sign.
