Astra driver#126(Astra ran some numbers; this is a partial quote)

Add these two numbers together, 4,400ft to go and 5,400 to stop and you get 9,800ft total.

Total distance from the start of the runway to the gully is approximately 8,900ft
(7,011 ft + 1,000ft overrun + ~890 ft to the gully)

Not saying that there weren't any other failures during the abort, just that a considerable overrun was a certainty with an abort started that far past V1 even with everything working perfectly.

It could be that “something” came unglued in the connection between the yoke and the elevator, but everything seemed normal in the cockpit, including the flight control check, when the controls in the cockpit moved normally. The ailerons and the rudder work - and feel - fine.

The “something” could have also interrupted the sense to the recorder that is leaving details on tape.

The ailerons feel fine on TO roll, and you can feel that through the yoke. It’s calm and so is the rudder.

At V1 it’s normal.

At Vr you pull the yoke back for rotation and nothing happens.

One or two seconds later . . .

You think “TRIM”, and try that, but that doesn’t work.

A shout – “something’s wrong” – and reject, but it’s already too late.

It would be interesting to know how long it took with max power, if that is what they were using, to accelerate to the speed where they started the reject.
