Liberation Times published an article by Condorman6, a Twitter user that is an alleged “senior level aerospace engineer.”
Condorman gives their theories on why disc-shaped craft, such as the Gimbal, appear to wobble. They also elaborate on why reported triangles craft don’t have this wobble. After that, they touch on spheres & tic tacs as well.
If Condorman is in fact a “senior level aerospace engineer,” this insight to how the inferred propulsion system of each classification of UAP is invaluable.
