It's interesting that all tested aircraft displayed longitudinal dynamic instability.

Where does this come from??



It is patently false as a generalization.

While many WWII fighters were unstable in very specific conditions such as in climb power with a specific speed range or landing configuration.... most were stable and met the requirements.

It is was very rare for a design to be unacceptable over the range of the envelope such as the Spitfire.
