An f4 could probably go But it didn't in the video. As to why they used an f4? Probably a heck of a lot cheaper than a 737 at the time. It would seem like there are plenty of scrapped 737s available[1] to carry out such a test. I'm too lazy to look up prices on these things, but I'd be very surprised if those were significantly more expensive than a scrapped Phantom.
