WWII stuff
So. Jimmy Doolittle, basically the first USAAF pilot to fly by instruments only, led Doolittle raid etc.
It turns out that during Big Week in February’44, upgraded Fw 190s were particularly effective against American bombers and Doolittle revised fighter tactics as a forward screen to hit fighters, then had them trail returning bombers enough to hit the less maneuverable 190s from behind. So he came up with and implemented a response *within one week*. That’s impressive.
