UFO 'believers' have - since very recently - videos released by the US military in which they say 'detections of this object were confirmed by multiple sensor platforms' and 'we cannot identify this object and have no speculation as to its origin' or whatever the exact wording is.
You know what I mean, the 'tic-tac' video. The narrative provided with that video confirms that the object/objects were detected by multiple types of sensor (visual, infrared, radar) and by multiple sensor platforms (aerial radar, aerial infrared, ship-based radar) and that the detections correlated.
With those releases the the UFO landscape changed, to wit, the US military is now a 'UFO believer.'
