Interesting reading throughout the thread. Any who have experienced delayed recoveries (I remember WWW's from 8000ft) considered the possibility of the altitude the spin was commenced at adversly affecting the recovery due to the air not being quite so thick? Came from an interesting discussion I had with an old and wise instructor when I was starting out in the game after the CAA consulted him about an instructor in another part of the country who was spinning with a student. The 152 aerobat didn't come out for a frightnening long period of time after numerous recovery initiations and (when the situation became more urgent) doors opening/power application/pair of them shifting their weight from the dashboard to the baggage area. And please no nonsense about the same IAS for a stall please.
