UFO-ers were using things like the rotation speed as definitive evidence of some like other-worldly advanced technology. Demonstrating that it was the glare/gimble brings it back into the realm of just a normal far-away plane. It also casts doubt on the expertise of the pilots/military who didn't realize what happened.

Except they had RADAR locks, experienced jamming, and had visual identification in some cases.

The whole “lens flare from a far away plane” hypothesis has been throughly debunked. You have to ignore evidence to reach that conclusion.

Isn't the visual identification and jamming from other events?

Can you share where it is best thoroughly debunked? The stuff linked so far in this thread (Friedman podcast; pilot Lehto analysis) isn't good.
