Asking as a complete neophyte - how does this reconcile with modern war planes being inherently unstable as far they flight dynamics go, without their enormous thrust capabilities? I’m just curious, I know nothing about the subject, but it seems that the solution we came up with is thrust, baby.
A key difference is that war planes occasionally want to be able to rapidly change their trajectories.
With sufficient thrust you can fly around in a cube.
Unstable fighters gives them much more maneuverability at the cost of “not returning to straight and level flight” that normal planes have.
It’s not directly related to how the wind goes over the wings.
