Stability and Control characteristics of the Early Mark Spitfires

Interesting, thanks typhoon, the boxed extract sounds almost identical to what Mark Hanna was describing.

The main undesirable characteristic noted was the "uncontrollable rolling instability" with the gun ports open and in a steeply banked turn.

It also adds that there was 'unmistakeable' warning in the form of buffet.
