A spitfire takes off and crashes because the pilot took off with coarse pitch set. I suspect this happened a few times. Does that make it a dangerous aircraft or an aircraft with a flaw that needs to be understood by the aircrew? The published spin recovery for Firefly works - it is utterly tragic that 2 pilots have been lost but let's learn from it, master our aircraft and all be better pilots as a result of their loss. Rest in peace fellow aviators.
