Hi, sorry for any english typo. Im looking for an old video, i saw it like 8 years ago, maybe more, i just remembered it another day. Its a footage of aircraft tracking an ufo similar to that footage that got famous recently, but as far as i remember its not on that thermal mode. The aircraft is tracking the ufo until the ufo goes straight to a mountain wall like it is going to crash, but instead it just vanishes, like it enters/go through the mountain wall. Back then when I saw the footage I though “oh thats probably fake” but now thinking about it. It got me wondering. So, has anyone else seen this footage?
