How's that possible it managed to fly with only one engine ?
Planes must be able to do this to be certified.
Well, assuming they have two+.
A C-172 isn’t gonna fly too far with an engine out.

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?
ETOPS accounts for oceans. Please read the link.

The "certain number of minutes" includes being over oceans. If you're too many minutes, you can't fly there. ("Minutes" are fairly large. I believe at least one Airbus aircraft is now at 4 hours.)

#36I have wondered in the past if the benefits of a 'jettison damaged engine' feature would outweigh the risks.

#39The 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.
Yes, hence why I said the press will focus on this because of parts raining down. An airliner having an engine issue and returning single engine though is a routine thing... usually without missing parts.

Generally transatlantic jetliners have more than 2 engines, although I suppose that’s beginning to change.
