I agree that some of the things proposed by To The Stars are way outside of what I'm prepared to accept. That said, is difficult to dismiss what David Fravor has be saying given his service record and that he was commanding the squadron at the time.
This article has some additional information and explains that another scrambled aircraft took the video after David's encounter.

Some interesting quotes from the Boston Globe article:
“It was impressive. It was fast. It was maneuverable, and I’d really like to fly it,”
“What’s unique about [our encounter] is we physically interacted and chased it,” he said. “We literally engaged it.”
