GO FAST video captured by a U.S. Navy

Don't know for sure - but all that wing doesn't make sense if it didn't fly.

the wings were for gliding from a hight (similar to flying squirrels)= off cliff faces/ high land mass etc.. the large claws & in some cases hooks were for climbing back up!! no one is saying they were never airborne! powered flight came later.. but like you say: 'don't know for sure' no one does apparently

Has anyone determined the size of this object and it's speed from the video footage? If this was a large seabird, we can determine that explanation as false by those metrics. I'm reading an article on TTS site and don't see these estimates. That's unfortunate as we would be able to joke.

The source claims the video to be only 1x zoom.., and the object is around 5 miles away. This would make the object much larger than a bird.

For the camera to register a bird sized object with 1x zoom.., it would need to be much closer. I am guessing within less than 1 mile depending on the cameras sensor and aperture size. But even the worlds best camera would not be able to detect a bird 8 kilometers away at 1x zoom.

Its possible to get the size of each 1 pixel in meters or inches if we knew the camera type. Or perhaps we could just run the math against a variety of different camera stats and see how big 1 pixel is for each.., then go from there?

Hmm, I think I got it. My 1st attempt anyway. I just chose specs for a really good camera circa 2015.

Sensor size physical height: 40 mm - (Imax is 52 mm) Compare digital camera sensor sizes: 1″-Type, 4/3, APS-C, full frame 35mm
Sensor's picture height: 4912 pixels (common HQ DSLRs) Camera tech data for Sony NEX-VG20E
Distance to object = 8200 meters (statute)
Object height in pixels: 6
Object width in pixels: 11

Height of real object:
Lens focal length 18 mm = 22 meters
Lens focal length 300 mm = 1.35 meters

Width of real object:
Lens focal length 18 mm = meters 40.5 meters
Lens focal length 300 mm = 2.45 meters

One thing to consider is the footage shown is at a much lower resolution according to the source.., which makes the object smaller.

We need to find out the video resolution we are seeing, get a size of the object in pixels, compared the output to the Raytheon AN/ASQ- 228 video resolution.., and estimate the upsize.

I.e. I would guess the footage is 480 and the camera recorded at 1080, which adds at least 2 to height, and 3 to width.

16mm lens: 33.9 meters X 58.43 meters
300mm lens: 1.78 meters X 3.12 meters
