First place to look when this sort of thing happens is pprune.org - lots of pilots on there, often with specific knowledge of the aircraft type and/or of the incident itself. In this case: https://www.pprune.org/accidents-close-calls/672872-ryanair-...

That top reply made me laugh out loud:

“>Glad it turned out well.

>Wonder what the Ryanair social media team is going to do with this one

Ryanair introducing new additional charge to have a window.”

Well, this isn’t very typical, I’d like to make that point. Look, the windows not supposed to fall off, for a start. These things are built to rigorous aeronautical engineering standards — cardboard’s out, cardboard derivatives, no cellotape, no string. So chance in a million, really. And to be clear, the plane that the window fell off was flown to safety. So there’s nothing out there but birds, air, wind and clouds……

I just want to make the point that this is not normal

Earlier quoted context omitted.

"Low probability very high consequence situation has never happened to me, therefore I needn't do anything." -- someone who doesn't understand expectation in probability.

They even put a "/s" at the end of their comment...

I wasn't referring to them directly, so I have plausible deniability.

The window didn't "fall off". In article's 1st paragraph: "debris from a dramatic engine failure caused damage to the aircraft's window" That's high-velocity pieces of metal. Hard to prevent that from shattering a window if engine housing didn't catch it. How much stronger, thicker & heavier you want to make those windows? Costing how much more fuel? To save how many lives per year? I'd think airplane builders (note:…

The comment you are replying to is a reference to a famous comedy skit (about the whole front of an oceanliner falling off, and the official company response).

I could see this being a safety issue if there’s a problem with the wing or engine and the panels fail, so zero visibility. Its why they ask you to open the window blinds during take off and landing

It's also so that rescue personnel can see into the plane in the event it crashes.

Odd. Rescue personnel aren't typically high enough to see in through the windows.

Extremely similar to Southwest flight 1380 which killed a person in the US after they were partially sucked out of a broken window from an engine failure. https://en.wikipedia.org/wiki/Southwest_Airlines_Flight_1380

And both were Boeing 737s ... (albeit different variants)

The Alaska Airlines flight that had a door fall off was also a Boeing 737

Fan and turbine failures are supposed to be contained by the engine casing - it's part of certification. But as we see here, uncontained failures do occur. In general "airplane builders" do the absolute minimum to meet certification so they're not going to add reinforcement to protect against such an event until they're forced Into doing so by the authorities. Turboprops can't, of course, contain a propellor failure…

In the case of the Quantas A380 departing from Changi some shrapnel from the engine explosion did go through the aircraft's body, cutting cables, making a mess of the control-command systems. I don't know how one could contain the kind of energy imparted to these metal bits, especially on engines with so much power...

I thought that the speed of the air moving outside of the plane had a bigger impact on the pressure imbalance that causes someone to be "sucked out" of plane. It appears that is a false belief, the inside/outside pressure difference is from the artificial pressurization of the internal cabin. I blame a high school physics teacher for the memorable "why does a soft top convertible poof out when driving fast?" question…

I learned about the artificial pressurization not too long ago. But until I read your comment, I assumed that in a case like that, the inside and outside pressures would balance shortly and the sucking would cease. Now it occurred to me that maybe the pressurization system will continue to try to compensate pressure in a situation where pressure can´t be stabilized due to a broken window, which would cause the suckin…

I believe standard protocol is for the pilot to reduce altitude until they are at a pressure that is fine to be at (<10k feet). Then they can make an emergency landing plan (or burn off fuel as in this case)
