      Oh, he briefly rolled the wrong direction before correcting and trying to pull out. Or he didn’t complete the roll properly.

      Whoops.

    2. looks like he didnt rotate fast enough and his momentary pause upside down led to the plane descending more than intended. after finishing the rotation the planes momentum was already going downward and by then the plane was too close to the ground to correct itself.

    3. During the roll while inverted, pitched “up” too early, dropping altitude, and was too late too low by the time it was upright.

    4. Was late on the roll, then hit it too hard and didn’t get enough thrust in the right direction to compensate. That could be anything from pilot error, to mechanical fault, to software blip, to surprise changes in air condition. No way to know without a ton more data than just the video.

    5. For a hot second there I thought I was watching videogame footage. It just looked odd seeing the videos synced like that.

      Not sure these are comparable. The 2022 plane continues to bank, which would have only made the 2025 plane hit sooner. I think 2025 plane just didn’t have the altitude for what he wanted to do. Do we know the altitude of the 2022 plane?

    7. Well, I’m not pilot, but I’ve flown a lot of RC aircraft. It looks like the one that crashed gave it “up” elevator instead of “down” elevator when he was inverted and didn’t keep the rudder pinned to the left to counteract the yaw created by the elevons. Also looks like he started the whole maneuver too low.

    8. Sink rate during the roll. 

      When it was rolled through inverted, the nose noticeably dropped.

      There’s an interesting analysis by a military pilot on YouTube who said he knew display pilots who were ordered to change their display routine, as a manoeuvre like this had too much risk / not enough of a safety cushion.

      So it was supposed to be an aileron roll. But it became a barrel roll, because he didn’t use rudder for some reason (failure?).

    10. The pilot could have probably ejected way early but the aircraft going haywire into the crowd stopped him from do so.

      I just watched somebody die and everyone is joking about it.

      Y’all need to get a grip.

    12. To everyone asking “why didn’t he eject”: Pilot probably didn’t even realize how close to the ground he was. And even if so – he had max 1 second to decide.

    13. He didn’t complete the roll as intended, and when pitching up to do the left turn as seen on the left hand video, was instead diving into the ground. He simply didn’t have enough time to pull out of that, at that point.

      He could’ve maybe saved himself if he immediately ejected when he rolled upright, but I don’t think he had enough time to process his options.

    14. What about the little flash towards the front of the jet we see immediately before the plane dives? I assumed something electric or some sort of tiny explosion happened that led to loss of operational capability

    15. Between the left and right video, when the left plane rolls inverted, the afterburner ignites but in the right video it does not. Instead, it begins smoking and by the time the plane has righted, the smoke increases dramatically. I wonder if it is not smoke, but vaporized fuel that didn’t ignite. If the pilot didn’t get the sudden thrust boost from the afterburner which might have been needed to increase airspeed, he just stalled and dropped like a rock.

    16. This helps a lot. That nose dipping seems to be the main difference, specifically at that altitude. It looks like it was enough to lose precious altitude once that happened.

    17. Lots of theorists here, but are there any professionals or pilots here that could give a more educated guess as to what went wrong?

      To me it looks like the roll was too slow, leading to him being pointed at the ground for too long and losing too much altitude. But I assume there are a number of malfunctions that could have caused that as opposed to just user error?

      Someone more educated than me needs to chime in lol

      Yes Reddit will know why he crashed like they had every wrong theory about the Indian passenger jet crash – ground effect indeed.

    19. There is a slight wrong turn which becomes an over correction and then it all becomes to slow at that height.
