Stability and Control characteristics of the Early Mark Spitfires

Unfortunately for you there is little if any evidence of any bad outcomes.

J Quill in June 1941 they did tests re wing failures. So until then it wasn't a noticable issue or the tests would have started in say Oct 1939

X4381 lost a wing in a dive. Quite possible when exceeding the dive speed

X4421 lost its wings when in a high speed stall after a steep dive ignoring the pilots notes

X4354 lost its wing in Dec 1941 at an OTU when in a dive. An old aircraft in a training unit in a dive probably exceeding the dive limitations

X4381 lost its wing in an OTU in a high speed dive out of cloud. An old aircraft probably exceeding its dive limits after loss of control in a cloud

Is that the best you can do?

PS what about all those that broke up when spinning, another major weakness (according to you)
