The press will make a big deal out of this because of the spectacle of parts falling on people’s lawns... but other than that this looks like a fairly routine engine out situation. Nice job by the crew.

Uncontained engine failures are a big deal. Exactly because they're a risk to the plane, as debris can cause other failures, and a risk to people on the ground. Engines are specifically tested to see if they can contain these failures. This doesn't seem routine at all.

Lucky it didn’t happen half way. Could have been several hours on one engine and the other one shaking and on fire.

Luckily flight plans are always required to be within a certain number of minutes of a place to land, and are certified to operate on one engine for that period. https://en.m.wikipedia.org/wiki/ETOPS

How do you account for oceans?

I really appreciate focused news sites like avherald. Just the facts, a collection of photos and videos, straightforward. The video of the landing & the passengers cheering—- that huge sigh of relief. Brings a smile to my face.

What, you don’t like the anchor people on TV asking each other how they feel about every piece of news and making horrible puns at every opportunity? Or having expected announcements be reported as BREAKING NEWS?

i think in part by having more than 2 engines on those flights

By having airports on islands, or by pushing up the number of minutes that the engines/operator are certified for.

Transoceanic aircraft need lots of ETOPS time. For example the boeing 777 (twin-engine, transoceanic) has an ETOPS of 330 minutes, so it always needs to be 330 min away from an airport (which is 11 hours of flight from airport A to airport B, not taking wind into account)

I worked at a Large Internet Infrastructure Company for a long time, and saw software development practices that made my hair curl. All I could think was, "Gee, I'm glad we're not working on aviation software!"

Seriously, though: software "engineering" could actually earn the name, if we had rigorous professional standards, regulatory oversight, and product liability.
