Technically, what she did wasn't special. But as someone with flight anxiety and occasional panic attacks, I would find it hard to be calm down in that scenario, especially when there's a hole in the fuselage and a passenger sucked out.
What defines hero is debatable though.
I equate it to driving a car. When I was a student driver everything was new and nerve racking. I didn’t develop any muscle memory yet.
20 years later I had all the basics down, but that was driving 60 mph. One drive on the Autobahn at double the speed made me realize there was a new skill I had to learn.
Now compare that to a professional race car driver who is taught, and practices again and again until it is second nature. They are perfectly calm driving 200 mph in close proximity with other cars.
Fifth uncontainted engine failure in less than three years
This latest incident is actually the fifth uncontainted engine failure in less than three years.
British Airways Flight 2276: a Boeing 777-200ER flying from Las Vegas to London in 2015 suffered an uncontained engine failure on its #1 GE90 engine during takeoff, resulting in a large fire on its port side. The aircraft successfully aborted takeoff and the plane was evacuated with no fatalities
Southwest Airlines Flight 3472: a Boeing 737-700 flying from New Orleans to Orlando in 2016 suffered an uncontained engine failure on its #1 engine during climb resulting in a puncture to left side of the fuselage causing a loss of cabin pressure and damage to the wing and empennage. The aircraft diverted to Pensacola International Airport, FL for a safe landing on runway 17 about 20 minutes later without further incident. There were no injuries.
American Airlines Flight 383: a Boeing 767-300ER flying from Chicago to Miami in 2016 suffered an uncontained engine failure on its #2 engine during takeoff resulting in a large fire which destroyed the outer right wing. The aircraft aborted takeoff and was evacuated with 21 minor injuries, but no fatalities.
Air France Flight 66: an Airbus A380, registration F-HPJE performing flight from Paris Charles de Gaulle (France) to Los Angeles, CA (USA), was enroute at FL370 about 200nm southeast of Nuuk (Greenland) when it suffered a catastrophic engine failure in 2017. The crew descended the aircraft to FL310 and diverted to Goose Bay, NL (Canada) for a safe landing about 2 hours later.
Southwest Airlines Flight 1380: a Boeing 737-700 flying from New York to Dallas in 2018 suffered an uncontained engine failure on its #1 engine during flight, damaging the fuselage and resulting in a window failing explosively. The aircraft landed safely in Philadelphia with some minor injuries and one reported fatality.

When I drive, I don't believe it's likely to crash soon.
I would say sitting before the engine or the last few rows of the place would be the safer bet from incidents like this. Thankfully neither of these planes ended up with a giant gaping hole in the fuselage
The National Transportation Safety Board (NTSB) concluded that the accident on the Aloha Airlines B737 was caused by metal fatigue exacerbated by crevice corrosion. The aircraft was 19 years old and operated in a coastal environment, with exposure to salt and humidity. During an interview, passenger Gayle Yamamoto told investigators that she had noticed a crack in the fuselage upon boarding, but did not notify anyone.
For the aircraft production number 292 (B-737) and after (the aircraft in the accident was production line number 152), an additional outer layer of skin or doubler sheet at the lap joint of the fuselage was added.

Of the oldest Southwest Airlines B737-700s starting with line #1 (21.2 years old) that is the third one to have a major failure

Fatigue cannot be inspected. All that can be inspected, is to see if fatigue cracks have already started in the part. The manufacturer, Safran/GE, has miscalculated the fatigue life of the titanium blades. The planned life of the blades must be reduced, and new blades should replace older blades. Inspection of parts is not adequate to insure safety, and the FAA is a major fail, putting corporate profits ahead of human safety. The FAA is doing what GE/Safran wants, not what is required.
The fan containment ring failed. The FAA should force a redesign. Oh, that would cost GE money, so won't happen.

Unlikely. There have been large numbers of these fans run to end of life without problems. There have been a few failures but the vast majority make it through to the replacement point. That would suggest there is also a random failure mechanism driven by an unknown cause. These things will never be perfect. Birds will assure some failures. But the rate is low enough to live with.
It might also be good to note that SW has been cancelling some flights to get engines inspected. Probably running down and checking all the ones with high cycles on them.

No. Material properties are statistical. The fact many engines meet the desired life is irrelevant. Usually aircraft engine parts are designed to minus 3 sigma reliability. There should be no failures. The few failures is the problem. Note other manufacturers do not have this problem. There is now physical proof that the fan blades should have an earlier retirement life.
Bird strikes are a problem, but this failure was not due to a bird strike.
The rate is not low enough to live with, since this catastrophic failure was entirely preventable if new fan blades had been installed on the engine.
