A dark silhouette appears to turn against the clouds. Community analysts and independent researchers have built competing explanations around camera optics and flight geometry.

The camera hypothesis

Mick West’s community explanation argues that glare and the camera pod’s rotation can account for the apparent turning. Contributors compare background patterns, small camera movements and the timing of the changing silhouette. That is a testable optical explanation, not an identification of a specific aircraft.

A reconstruction from the sight lines

A separate research preprint reconstructs possible flight paths from the available viewing geometry and discusses the distant-jet glare interpretation. Comparing these approaches means examining their assumed ranges and camera behaviour, rather than merely choosing an impressive animation.

A useful way to watch

Keep the clouds and the whole screen visible. Look for a change in the frame just before the bright or dark shape changes orientation. Then replay the same moment with the competing interpretations in mind. A successful explanation should account for the background as well as the centre.

One sight line permits different paths

Yannick Peings and Marik von Rennenkampff reconstruct possible paths as a function of range. Their 2023 preprint obtains an unusual reversing trajectory at the distance reported by aircrew, while also discussing the alternative of a distant jet and infrared glare. Those are conditional paths, not two separately observed flights. The witness-supplied range and the camera-derived direction play different roles; the public clip alone does not supply an independent range measurement that selects one reconstruction.
