The 'Great Debate' - Spitfire vs BF109

[winny]

Here's what Geoff Wellum says about it (BoB veteran).

However, in a Spitfire, just before the stall, the whole aircraft judders, it’s a stall warning, if you like. With practice and experience you can hold the plane on this judder in a very tight turn. You never actually stall the aircraft and you don’t need to struggle to regain control because you never lose it.
