Aborted Takeoff at Zurich - October 2023
Saw this and thought it was interesting, Edelweiss A320 Zurich to Faro, Portugal, with a massive left turn on takeoff and nearly runs off the runway. Big left deflection of the rudder.

The ol’ chicken or the egg…
Did the blown tire cause the abrupt left yaw or did some other factor cause the abrupt left yaw that resulted in the blown tire? I don’t recall seeing a a blown tire or even an engine failure at that speed resulting in such an abrupt yaw. Watching the video, I see a large left rudder defection immediately proceeding the left yaw. PF got the jimmy leg?

Yes it does we appear to be looking at the aircraft directly from astern, but several degrees off the runway centreline
Watched it a few times and I can't avoid the impression that the rudder deflection precedes the onset of yaw slightly. If there was a crosswind from the left, as appears to be the case judging from the slight deflection of the rudder to the right and the crabbing nature of the track, there does not appear to be a need for a large left rudder input... but that's just the theory from behind a keyboard.
Definitely a left crosswind on takeoff. When going fast on the runway, jets will weathercock a little into the wind, requiring opposite (in this case, right) rudder to stay on the CL.
Agree. It looks to me that something rapidly jammed on full left rudder causing the rapid yaw left, and almost immediately after, corrective right rudder was fed in.

There is plenty of smoke from all tires. However, the smoke doesn’t begin until after the yaw event begins; e.g., the right main gear tires don’t begin smoking until crossing the centerline. Initially it looks like the tire smoking is due to extreme side loading. Even the nose gear tires are briefly smoking after the yaw event begins (the Michelin engineers are either high-fiving or throwing up their hands in disgust). The tire smoking also appears to be proportional to the change in lateral loading from the yaw event. During the right yaw recovery, it appears the right main gear tires may briefly lift from the runway.
