Hi Toonces3 and friends!
The video is an animation.
And History Channel's animations, usually are not accurate.
The P51 in that video does a "helicopter" move. VERY low forward speed, kick on left rudder and consequent rotation around vertical axis(yaw).
If one does that in a high performance airplane, very low fwd speed, i.e., near stall, and kick rudder, chances are that the plane goes into a spin, and a flat one , by the way... Most of the times, impossible to come out.
I do a different manouever. Letīs say, I'm on a Pony or Yak-9U, fighting a Spit VIII, A6M or any other tight turner.
Enemy passes by and enters a TIGHT left turn. I know I won't be able to follow him into that turn.
I point nose down and look UP, or FORWARD+UP to keep my eyes on the enemy and do an aileron roll, following enemy direction of turn(in this case, left).
When my gunsight is ahead of enemy, stop the roll, pull nose up and BAM!
Will rummage through my AH films, when I find a suitable example, I'll post it here.
The manouever as seen the History Channel film cannot be done exactly as it is shown. IMHO.
