Agree, RF84F given the large wingroot intakes and four strakes along the tops of the wings. The other is a mystery. It's obviously a twin engine design with straight wings but in a couple of frames it looks like it has two tails while in a couple of others it looks like a single tail. Given the almost straight leading edge and significant trailing edge taper anyone want to guess F7F?
As for the video itself, it's yet another ridiculous riff on Area 51 starting where they considered it sinister that the control tower at Inyokern (in California, not Nevada) isn't manned and there were no radio communications. Duhh, the CT was shut down years ago and it's an uncontrolled airfield which, of course, they would know since there's no tower freq listed in the pubs. They also include all these shots from China Lake which is over a hundred miles from Nellis and imply they're doing something sneaky by flying in "restricted" airspace. R-2505 (where China Lake is located) is easily crossed, just call Joshua approach. Same thing is true for a lot of the areas in the Nellis complex, especially on the weekends. You can fly right up to the edge of R-4808N which is where Groom Lake is located. Perfectly legal to fly in most of them even if they're listed as "continuous" operation provided you get permission and it's done every day. Lovely use of the sinister music though...lol.
