FLIR1 = distant-jet / IR-glare analysis (Mick West).
documentedanalysisScientific Instrumentation & Sensor Data
Skeptical reading that the FLIR1 Tic-Tac IR signature is consistent with a distant aircraft; absent slant range, the apparent extreme motion is unconstrained and not necessarily anomalous.
West argues FLIR1 alone proves little: the IR blob is consistent with a far-off jet, and because the clip lacks laser/radar range the implied velocities and accelerations are not pinned down - small changes in assumed distance swing the derived kinematics enormously. This is the weakest-resolved skeptical claim (it is a plausibility argument, not a closed solution), and it does not address Fravor's separate visual account or the radar tracks.
