It was a Bell P-63 Kingcobra, not a P-51.
I posted the very same thing just a few posts later. I think I was the first in the thread to do so. The shape of the P-51 wing did not match the plane in the video, so I looked for more news stories.
The pilot’s eyes are even further ahead of the wing’s leading edge on the P-63 than the P-51. The point I was making is still valid. Fighter pilots have weighed in, however, explaining that something as big as a B-17 could hide under the nose of both fighters.
