Passenger Partially Sucked Out of Ryanair Boeing Window (Survived!), Greece, 7/10/26

Just so fortunate it wasn’t an infant sitting on parents lap as I understand is allowed without restraints.
 
"Okay folks, we are going to suspend the 'roll-down window' air conditioning reduction initiative - for now."
 
Between this and southwest 1380, it does not seem that the fan casing on the CFM56 has a great record recently of doing its job and containing a blade out event.

After the 2018 Southwest 1380 mishap, the design and manufacturing processes for CFM56 fan blades were modified, and the 737 engine nacelle containment structure was strengthened and expanded.

During the eight years between that event and the Ryanair incident earlier this week, the 737 fleet has flown somewhere around 32 billion miles (~34 times the distance between the Sun and Earth) while amassing roughly 270 million flight hours. Accident statistics on uncontained 737/CFM56 engine failures since its introduction into commercial service on December 7, 1984 are not precise, but from what I was able to determine, the number is less than five.

These figures would lead to the conclusion that the 737 and its CFM56 engines are a particularly safe and reliable combination. In fact, Boeing has built more 737s than any other commercial airliner in history, and the CFM56 is the best selling turbofan engine of all time.
 
That’s not what I said. I didn’t say that it wasn’t safe or reliable, but we’ve had two incidents of uncontained fan blade failure. Given that blade failures are a rare event (would be interesting to know how many net failures of this mode there have been since SWA1380), it’s still not batting super well it seems. Something can be largely safe and reliable and still have an element which is not doing its job amazingly well. Now if there were 40 contained failures and 2 uncontained sure, not a bad job, but how many contained failures have there been in between SWA1380 and this?

I am well aware of the heritage of the CFM56.

So in your view, anything less than perfection is an unacceptable outcome?

I don't know if contained blade departures are reported and catalogued. I searched for an answer before making my post above, but did not find one.

Sigh. If you’re not going to bother to read my posts, I’m not going to bother continuing this discussion. Have a good day.
