I'm literally learning about this "gimball video" from this video, so I don't have all the background, but the video we're looking at wasn't taken by David Fravor; it was taken by Chad Underwood? In the video we're looking at, we don't so much have to guess how far away the object was; the camera video itself indicates it. It's too far away to discern shape and rotation accurately with a naked eye. The video goes into detail about this, and the details aren't complicated.
yeah I made a mistake and can't edit my comment. You are right the gimball video(OP's link) was from 2014 and was not related to David Fravor. Its confusing as there were three videos released at the same time in 2017 and they all came from the Pentagon(and were all black and white). David Fravor's incident(2004) was an eyewitness of him seeing the unidentified craft and there was a video taken by Chad Underwood in FLIR of the object. This same object was also seen on radar multiple times by the carrier group he was a part of and was the reason he was sent to investigate it. A link to all three videos and their details:
Spoken like a true none believer. I shun thee. Even the pentagon said they can't explain the UFOs, clearly they are preparing society for a big reveal. ;)
Edit: I'm betting half the downvotes are from people not picking up on my sarcasm, and the other half is from people picking up on my sarcasm.
