While the "go fast" video might be a balloon and we lack enough evidence for the 'gimbal' case to dismiss his explanation (or metabunks for that matter) completely, the Context of the 'flir' video, beeing multiple people observing strange tic tac shape crafts (fravor and the other female pilot, so far unnamed), multiple radar systems picking up on them as confirmed by the princeton radar operator and the flir video showing what are possibly unheard of flight characteristics as analysed in this paper https://www.mdpi.com/1099-4300/21/10/939/htm make these superficial debunking claims rather tedious if not outright disingenuous.
The broader group of researchers, who are open to anything from atmospheric physics phenomena to straight up aliens, are worth giving a listen regarding his debunking. IMO they ask good questions.
The only question in my mind is whether the USN is filled with fools who couldn't figure out what he figured out, or whether they're deliberately fucking with us. I'm strongly inclined to think it's the later.
If they could identify these objects, why lie?
If they could not and these are in fact explainable as known craft/balloons, doesn't that imply a serious security risk?
Most likely, IMO, guided MRVs being tested. ...that's why the folks at ArmsControlWonk are suggesting as well.
