glide approaches should be taught from the very first flight to build up skill and judgement
There was a time (1930's?) when spot landings were a requirement for issue of a PPL. Procedure as I recall was climb to a given height, close throttle, and touch down on a pre nominated spot. Accuracy determined if you got a tick.
Pity that skill has been consigned to the history books. Glide approaches were the norm in those days
You can do them in a jet, just don't forget the gear.

Checking I found Len did put his "Flying" magazine articles into a book. Also a book on the 727 in company with his son.
