Actually they rounded up witnesses who were pilots right after it
happened. I was among those who identified themselves and the NTSB
started interviewing people. After they talked with several people
individually they announced that they had good video of the accident and
wouldn't be needing us.

Since this video was only taken with a digital still camera, it's not
very sharp and only 15 FPS. I'm sure they got something taken with an
actual video camera that's much clearer.

I'm not looking to make anything off of it. I still get a bit of that
sick feeling when I watch it again. I just don't want someone else
copying it and selling it as their own.

This is always a judgment call. It goes without saying that the RIGHT
thing to do is to check with the NTSB first and let them see it as it
could aid in the investigation. The commercial end of the equation is
that you might be able to generate some income from the clip by hawking
it but that's doubtful at this point.
Naturally being involved in P51 flight safety, my advice is to call the
NTSB immediately and vet the film with them as soon as possible.
Thank you if you choose that path.
