        The 767-400ER was first introduced in September 2000. Where do you get your probabilities, plane expert?

          The fact that this plane was built in 2000. The fact that lemmy is representative of Reddit user demographics and their average age is 18-29 making it a reasonable assumption that you are under 25.

              You are a fucktard. I know how to look up tail numbers and info just as easy as the next guy. This plane was built in 2000 according to the info available.

    Was it just surging or like a compressor stall or something? FOD like a bird ingestion or something?

    I mean, Boeing has/had quality problems, serious ethical failures, but also birds exist.

    (I’m not good at explaining this, maybe should have found an explanation online somewhere instead.) You know those stages of a combustion engine - intake, compression, ignition, exhaust, all happening in sequence in an engine’s cylinders? Turbine engines do them too, but in a straight line and constantly. The front of the engine is obviously intake, but compressor fans do the compression just using fast and powerful fans, no seals or valves needed. Ignition lights everything up, exhaust can just flow out the back. (It flows over some more fan blades that steal some power from the expanding gases and use it to keep the whole thing spinning.)

    Unless something goes wrong with the compressor fan blades, that is. If compression is too weak and the ignited air/fuel mixture can flow back out the front of the engine, that’s bad. And yeah, it happens sometimes, with any engine. Almost never with both at the same time. (Both engines failing at once low to the ground is like a once in a generation thing, and yeah it’s really really bad. And really really rare.)

        I’m sure an engine would have just as tough of a time with a spy drone as with a hypothetical flying animal XD

      I have seen news stories describe engine surges as “bursting into flames” before, but that’s not the case here.

      The video of the incident shows a small but sustained flame emerging from the bottom-rear of the engine, well below the engine’s core.

      There was an engine fire but in typical journalistic fashion it was far short of bursting into flames.

      Unlikely to be boeing’s fault as they don’t make the engines, just the airframes.

      Edit: An engine surge/compressor stall is the plane’s version of a backfire. Big bang and a burst of flames. Very exciting, but very little danger beyond the loss of thrust. This incident wasn’t a surge, but the last time I saw mainstream news say an engine “burst into flames” it was.

    I’m not going to fly Boeing. I don’t trust the US to have enforced strong and transparent building standards. EU with Airbus all the way.

    I can just hear the Trump reprobates advising their supporters… “If we cut Regulations further, we something something something and MAGA! Fuck the Commies.”

      Delta flight 446 landed safely, and the plane taxied to the gate on its own with no sign of a fire at that point. Passengers were able to deplane normally…

      Delta said customers were reaccommodated on a new aircraft to their final destinations.

      This was little more than an inconvenience for the passengers. The news always uses deliberately alarming language to entice a click. There was an actual engine fire this time, but it was a small one that appears to be out before they landed.

      Commercial aviation is orders of magnitude safer than cars. The occasional incident is national news because they are rare. Fatal car crashes happen so often they aren’t even newsworthy.

        Oh, just a small engine fire. Gotcha. My bad, that’s cool then. And definitely no recent pattern of problems with Boeing planes either, so that’s also good.

          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.
