The above is incorrect.

Demonstration of unpowered 180 degree turnback to the takeoff airfield from
altitudes as low as 200 ft was required of my fixed wing student pilot
training curriculum. I've done it in a real aircraft.

My experience was not rare, either. All the CFIs I've flown with have done
it.
