Good points 2R, excpet for your comment about the 'challenge' to stall a modern aircraft.
People keep stalling them by mistake, regardless of configuration, power, AOB, time of day, generally at a height not sufficient for recovery, and they pay the price for it. Half of them probably never figured out what was happening.
And the so called magical 'stall speed' is only a 1G speed, with the slip ball in the centre.
In my opinion (and I've been through both civilian and military flying training) these more extreme stalls should be practised - in an aerobatic aircraft if neccessary.
