The engine is located far from the passenger cabin and it has fire suppression systems that probably put out the fire in flight. They have procedures for this that handled the situation so well they didn't even have to evacuate the aircraft.

Fires are a risk with any combustion engine. Clearly they mitigated that risk effectively since no one was in any real danger

Boeing doesn't make the engines.

So do you want me to compile a list of recent vehicle recalls and the alarming amount of cars that just spontaneously catch on fire?

How about the amount of biking deaths?

If you search up ATC recordings on YouTube you can find that go arounds like this are fairly common. If you're really afraid of Boeing's systemic issues, understandably, avoid flights with Boeing planes and you'd be fine.

An engine fire of any size is a serious emergency, and Boeing's recent safety record should get executives fired if not jailed. That said, commercial aviation remains the safest way to travel long distances. Incidents like this are newsworthy precisely because they are so rare.

Engines have nothing to do with the airframe.
