I have a lot of respect for Gordon Cooper. His Mercury mission was a remarkable feat, of piloting (he had to steer the spaceship back to Earth himself, when all his systems failed) and he made remarkable observations from orbit, demonstrating a visual acuity of 20/12, which is better than the average by a very large margin. If anyone should be able to see a UFO clearly, Cooper would be one of the best observers.
But, he was also a veteran teller of tall tales. He exaggerated some of the details of his Mercury mission, and expanded his role in the White Sands sighting beyond all credibility (
as we have discussed on this forum in the past). The only really unexplained sighting he made was one in Germany as a pilot, and there are unfortunately no corroborating records to back up his story. So we have to rely on Cooper's excellent eyesight and nothing else.

David 'Sex' Fravor is another character like Cooper, it seems, A great teller of tales. The only reason his story is so well known is the film taken some time later by Chas Underwood in a separate aircraft, and this film seems to be explainable by non-extraterrestrial events.
Here's Mick West on the subject of the Navy videos.
I think the FLIR1 clip taken by Underwood is pretty much explained, and the clip known as GOFAST is a good demonstration of the sort of mistake that Fravor was making when he saw his 'tic-tac'. As West has pointed out, the fact that the 'tic-tac' was not detectable on the plane's radar is not necessarily an indication of jamming, it is just an indication that the phenomenon was not where he thought it was.
