But like you mentioned his CoG was clearly to the front as his nose is already point down slightly. What I experianced was much the same, but without the happy ending. (Or recovery the first time)

You know what he did... I can see how this would recover but it is still by pure luck... He cut the engine completely in hopes that without the power the nose would drop, which it did, and just in time to. Sadly, because the altitude which it finally recovered was so low, he could not execute a proper forced approach and the plane crashed. This was a lucky recovery! The problem with a completely flat spin is that there are no aerodynamic forces working on any control surfaces, making any control inputs useless... Good find though!

So I pose this question, where are you getting this information?!

Wondering this myself. There seems to be some bad gouge floating around the forums.

Another big factor would be the intense disorientation he was experiancing. He stated (either in the info or comments) that he could not read his instruments and when he was "level and steady" the plane realy was rocking and at an angle.

In a left hand spin, throttling up the engine will break the spin of a single engined aircraft due to engine/propellor torque. On a right hand spin, it will make it worst.

Not necesarilly.. depends on the direction of rotation of the propellor. There are aircraft which have props that rotate counter-clockwise.

Yep, that's very true! Although instruments are not as important if you have outside visual. It's called VFR which is visual flight rules. This means your flying the plane with reference to outside and not the instruments (although you do check them from time to time). It would suck to get into spins or spiral dives on an IFR flight although you do learn to recognize them from the instruments. The big factor here which comes from what your saying is the human factors of being able to handle those forces and disorientation that your body is experiencing. But yes, very good point thank you!
