Thanks for the info there Zulu. I'd read about the Zero, but only in analogy. Nice to have technical material to look at. I'll have to see if i can find the book you reference.
But as for G LOC, at least as it was taught to me, it only relates to the loss of consciousness, not the immediacy of its onset. Blackout will lead to G LOC if the situation continues. So my previous post was wrong there, it didnt read the way i meant it. Sorry about that. What i meant was that you can reach G LOC either after blacking out, or immediately. But G LOC is the process, not the end result.
Id direct you to the centrifugal tests that were conducted on astronauts. Symptons went through grey out, black out and full loss of consciousness. And thats where the term originated. Moreover, the Goose Bay crash was the only crash where G LOC was determined to be the cause, but that doesnt mean it was the first crash where it was the cause. And even in the report that you quote it has the following "High positive g interrupts the normal flow of blood to the brain; g induced loss of consciousness (GLC) occurs as a result of brain tissue hypoxia. Because the retinal arteries collapse at a higher eye level blood pressure and hence at a lower g level, loss of consciousness is usually preceded by "grey out'' or "black out.""
You may also be interested to know, assuming that you dont already, that the Stuka had an automatic pull out system after the dive. The reason this was incorporated? Pilots were losing consciousness in the recovery from the dive. It's not a new phenomenon.
