Trying to find a recent video of a triangular craft activating some sort of warp medium.

I saw this video a few weeks ago and I cannot for the life of me find it again, it was possibly on r/ufos, r/UFOB or High Strangeness or a link from one of these subs.

It’s a short clip and it seems to be someone filming a video screen swith their their phone, it is very clear and sharp there are at least 2 people watching the screen but no visible detail (uniforms etc).

The clip on the screen shows, very clearly, a large classic “black triangle with a white light at each edge you see the underside, then it levels closer to the camera and on the top you can see two inward pointing wings or control surfaces similar to those on an SR71 Blackbird, I think one of the voices mentions that this makes it clearly advanced human tech and not NHI created. You start to see some flashes of light around the base, a voice mentions that there is a pilot in the craft and he is activating something. Then on the underside of the craft, at the centre, a large ball of bright light swells down and the craft disappears. I think I remember them saying something about this being a transportation medium.

The whole screen was greenish suggesting the clip they were watching was infra red or night vision.

This is driving me nuts, I have searched and searched and cannot find it again, does this ring any bells with anyone?
