h = 25050 ft = 7635 m (altitude of aircraft). For a more exact value, we'd need to know the air pressure at the time from weather data. Elevation of Alexandria: 23m Consider the triangle formed by the observer O, the aircraft A, and the center C of the Earth. The angle at O is...

So, given the Barksdale distance, the camers could be located at Fort Polk South? And then the tanker track would fit the observation if the clock of the "actual camera" (see post #27) is slow by a minute? (See https://www.metabunk.org/threads/accuracy-of-camera-clocks.13036/ ) If @eyeSpy wanted...

I think this means that the video was taken in landscape mode, with the horizon parallel to the bottom edge. Could you confirm that, please?

squares and parabolas are oriented, circles are not (in 2D). A corner of a square can point north (or not), try that with a circle!

Surprisingly, this is true. The "blow my mind" version of this goes, all circles are the same (except for size and location). Two triangles can [be] different, but two circles can't be different. And as Euclid's third postulate, this has been a foundation of geometry for over two millennia.

I think you are referring to this: Note I didn't put a scale on that drawing! It's not necessary. You're using a not so useful frame for your thoughts. In maths, the scale is not so important. If you draw two intersecting lines on a piece of paper, then the angle is going to stay the same no...

I am hypothesizing it's a group of aircraft, based on the geometry of the lights, and I'm looking for further evidence to support that hypothesis. I've also hypothesized it could be a pair of kites. However, they wouldn't travel across the sky in a straight line. You're hypothesizing it's a...

So, do they also put a transponder and an ADS-B transmitter on the UFO, then? And do they communicate with ATC? file flight plans? There is no half-way here. If you have that strobe, and another airliner sees you but can't find you on their TCAS, or if ATC notices you in controlled airspace...

The name denotes the Roman god of fire, volcanoes are named after him. The Avro Vulcan predates Mr. Spock by over a decade.

well yes the video shows the lights moving almost directly away from you, and then turning towards 3 o'clock knowing your approximate position, it's easier to determine if there are aircraft that fit this path do you check flightradar at all when you see lights in the sky?

We've been over this before. A responsible journalist usually gets confirmation from a second source before publishing anything. If there's no second person willing to confirm the story about the pilots, you don't print it. That's just standard procedure.

If they have TCAS or similar, having it on would generate constant alerts as the aircraft fail separation rules. This also applies to ATC. Hence, this rule:

If you're looking from behind, a lower aircraft could appear to be in front when it's not.

Shockwave from the aircraft.

that just means we have similar conditioning if you showed that clip on r/ufos, I'm pretty sure several people would independently arrive at the thought that it's a spacecraft :-p

That was my first thought as well. There is absolutely no reason to put a red strobe on a flying saucer, but every airliner has one. And honestly it's probably only a matter of time until @JMartJr joins this thread and explains to us that he's personally flown kites like this one (big...

First, @deirdre asking me something is usually pointless, because she knows she's on my forum "ignore" list, and it's only due to replies like yours (and sometimes random chance) that I get to see what she wrote. Secondly, I made two factual assertions: a), "The elephant in the room is that...
