I don’t have much of an opinion on this topic, I haven’t really looked into it.
But as soon as I saw this image, the El Al Flight 1862 which crashed in the Bijlmer in Amsterdam in 1992 immediately came to mind. The shape of the hole is very similar!
This image shows the likely position of the Bijlmer plane during the crash:
The image you posted of the Pentagon seems to me consistent with what I have seen of the Bijlmer accident, and so the shape of the hole and the absence of wings in the photo does not persuade me personally that no plane was involved.

I don’t know what happens to the wings of that specific aircraft when they collide with that specific building under those specific conditions at 460 knots. That’s a question for an expert on the subject, not random people on the internet.
