and if you look, he did that in the turn
by going high
which slowed him down
1 What would you call
a bend, where you go high instead of just banking and turning?
2 What happens to the seperation you created there vs the P51
when you subsequently come back down to the same altitude? right behind the P51 you spaced out from by going high in 1?
That's a yo yo
1 trades speed for altitude
2 reverse altitude for speed
That seperation is again lost if the P63 follows the P51 track from behind , because he is going faster then the P51
hence, he had to extend laterally or fly up their ass.
the flight track you posted doesn't show he was faster then the P51's, but maybe he thought he was.
Wind direction, P51s if wind came from behind P51's it would be coming from 4 oclock to the P63 so perhaps he didn't get the speed diff he thought he had on them
point remains
your video clearly shows a high yoyo initiated at this time
