    This is probably the end of the DC-10/KC-10/MD-11 platform. Metal fatigue related failure well before scheduled inspection. Don’t see any insurer, cargo operator, or private mid air refueling company wanting to be liable for this.

    Even if one of your jet engines decides to, um, just leave halfway through takeoff (jesus-christ), I thought these multi engine jets were designed to operate down an engine

      Likely engine 1 and 2 were both out, engine 2 has a visible compressor stall on takeoff visible in videos, likely from ingesting debris from engine 1. Two engine failure on takeoff is unrecoverable in a tri jet.

          It’s a very rare freak accident that happened on an aircraft type no longer used by passenger airlines, even before this. I don’t think this will have much of an influence on aviation beyond an early retirement for the MD-11. There’s no such thing as a risk free flight, risk is inherent to aviation, but lots has been done over the years to minimise risk.

      I think a lot of factors combined to make this deadly. Not least of which, the engine seemingly strikes the plane when it yeets? Further, it happens during takeoff, so the plane is completely oriented improperly for gliding while down an engine. And then finally, as seen in the video, the catastrophic destruction was due to the frame hitting structure and beginning to tumble end over end. Ideally, they could have slammed back down into the runway and skidded to a stop eventually.

      Not exactly the same but very similar. AA191 was caused by improper maintenance that weakened the rear pylon mount. We don’t yet know why the rear mount failed but this time but the prelim report claims the spherical bearing lug had metal fatigue cracks as well as signs of overstress, but doesn’t mention any dents like we’re present on AA191: (Sorry for the yt screenshot it was the only place I could find this picture yesterday)

      Also AA191 crashed due to assymetrical lift due to the slats retracting as hydraulic pressure was lost on the affected wing, this time iirc the slats remained extended and the plane just didn’t have enough thrust. It’s possible that debris from the engine separation were injested by the #2 engine causing it to lose thrust as well while the plane was extremely heavy.

    I was browsing Reddit for some reason yesterday and came across a post relating to this series of stills.

    My first and overwhelming reaction was closer to wonder or amazement (that’s probably not the right word but I’m not a smart man) at the left engine just sort of fucking off to go elsewhere instead of forward.

    Then I remembered that there were humans on that plane. A couple-few people just going thru the motions of a normal day for them. One more flight in a seemingly endless run of them. The ones on th ground who were just going about their normal day and maybe thinking about dinner, or trying to scratch their foot with their other foot because their hands were full…

    I wonder if the men and women who worked on that plane are thinking about what they worked on, did they overlook something? Were they themselves thinking about what to make for dinner, or thinking about upcoming car repairs when performing work on that particular plane, and overlooked something crucial?

    The whole thing is a tragedy on so many levels. I hope the families affected find some peace.

      I’m friends with some airplane mechanics including a couple people that work for global logistics companies. The mechanics who worked on that plane are not just worried about if they overlooked something: they’re potentially criminally liable actually.

    • Thankfully, this is probably a design/maintenance issue with the DC-10/MD-11 that doesn’t apply to other aircraft. The A320, 787, A350, A380, and 777 aircraft have nearly spectacular safety records. Flying is still the safest method of travel by a significant margin. Planes just fail in a uniquely scary and public way, whereas busses, trains and cars kill people in mundane and unremarkable ways.

        I do and I realize that, statistically, that is less save then flying. But if my car catches on fire, I can exit it and since I drive the same car every time I drive, I can notice if it needs repairs and whatnot. In a plane, I gotta hope that whoever serviced it didn’t fuck up.

        Also, most car problems, even crashes, are not deadly. I drive in the city and a crash even at 50 kph isn’t that likely to kill me. Meanwhile, any problem a plane might have is an immediate nightmare scenario.

        Sense of control vs no sense of control, I suppose.

          FWIW you also have to drive if you live in most places in the US. Flying is optional but there isn’t a way to opt out of the four-wheeled death trap like you can with air travel.

          i used to subscribe to the idea that flying was safer than driving and since i drove all the time, i should just zen out about flying.

          i drive way less now, but besides that, i think the undernining of the administrative state and its institutions is undermining the historic record for air travel safety, specifically the idea that historic statistics are a predictor for present and future reality.

          so, basically, fuck flying in the US.
