In my first post, I told it... quoting myself:

the few that succeeded and then developped the experience to master it and teach the others (as you can read in some WWI flight manuals) are dead today


you could have added that the spin recovery training started only late 1917 (so only in the last war year) and that even if a recovery procedure was developped, tested for some pursuit planes and teached, the whole phenomenom was fully understood only later (see my previous post).

In any case, in none of the flyght manual you give references to, the transition from stall to spin is explained in details (with all the initiating effects for all particular planes).
... and as I said, all the pleoples that spinned these planes are dead today.
