Looked like it could have been a bad incident - must have happened a second before Vr.

“When experiencing a loss of directional control on a wet runway, immediately cancel reverse thrust to idle and adjust the brakes. Full reverse thrust, particularly with asymmetrical deployment or crosswinds, can cause the aircraft to weathercock, slide sideways, or skid due to rudder airflow disruption and asymmetrical side forces.”

Would have probably snapped straight, but you’d have to hope the wheel brakes would have retarded it enough in those surface conditions.

I have a feeling two things happened. First the "oh fudge" moment when the view went from grey tarmac to green grass which had that startle reaction and second they were going so fast at that point that they were probably going for the ride anyway with the wet surface etc. I expect there was some level of "I cant do that Dave" from the flight computers given the control inputs you can see happening on the wings and the braking action on the wet grass.

Super interesting situation though and would love to see some photos of the fan blades!

Amazingly handled by the pilot.

No1 engine quit just before v1 which sent them grass ways. Can see the no1 engine is completely dead and reverse thrust was actually helping to pull them back on track.

Could have been a lot worse.

Many tons of aircraft on wet grass? The wheel brakes will have been next to useless without thrust reverse to help them.
