My armchair speculation finds it odd that there is no more discussion around unusually high airspeed and what is causing them early in the flight. E.g. it appears that both JT610 and ET302 hit ~300kts within ~2 minutes of flight[0][1] whereas on problem free takeoffs 300kts appears to be reached at ~4 minutes into the flight at around 10k ft[3][4][5].

So based on this, I would speculate that maybe there is some condition that leads to run-away thrust, makes pilots report 'flight control problem' about 3 minutes into the flight[5][6] and then the rest follows.

If the angle suggested above has already been investigated and there is some reporting around this - would appreciate pointer there.

Surely there's some kind of warning system that alerts if the flaps aren't set for take-off?! That'd be easy to write an alert for -- are the wheels-down sensors triggered, the throttle well above idle, and the flaps up? Fire the alert.
