That's what the parent says, and what the BBC inplies, but not what the UK report says. The pilot reacted at 1300 ft. It took another few seconds of falling to recover at which point they were at 928 ft.
Which is how i practiced things like apparent high speed stalls, where the indication is that you have speed enough but are still stalling, and so you dont trust the indicated airspeed. If you know your altitude and suspect a stall, you dont pull immediately for fear of triggering another stall. You biuld up some airspeed first. If you have it, you use the altitude.
