[New Perspective]

Have you?

Actually I have, many hours. Your analysis of vision presented by a fisheye lens is distorted. You do not have an understanding of what is visible.

I think it may be more a misunderstanding of how the fighter is actually moving relative to the axis (plural / all 3) of the plane. I can easily visualize the blind spot — it’s a bit harder to visualize vectoring right into it.

(Disclaimer - I am not a pilot, but this effect occurs in good video games.)

I’m noting on You Tube threads a few comments by air show pilots that it appears the P-63 was considerably to the right of the other fighters in the circuit the fighters were supposed to be flying. The pilot of the P-63 banking to get back in circuit might have put the B-17 right in the P-63’s blind spot?

For example, see the comment by one Jon Fox, here:
