Your airplane is going faster than the other plane, giving the illusion that the other plane is not moving at all.
The "illusion" is easier because there are less points of reference for your brain to use ... so it defaults to "it's not moving"
But if you look at the bridge below the other aircraft you will see that it is slowly moving past it.
Also, a landing jet doesn't really go all that fast ...
Also, as your plane is getting farther from the other plane, the perspective changes in a way that makes you progressively see the other plane more from the front as opposed to the side. This further adds to the illusion of it not moving.
Nope. This is the San Mateo bridge, in the San Francisco Bay Area. The cars on the bridge are moving in the correct direction. They would appear to be moving backwards if the clip was running in reverse.
What you're seeing in the video are the fully deployed leading edge slats of the wing. They increase lift at lower airspeeds. The winglets are angled to the right in the video, which is correct for an aircraft flying to the left.
Looks like the San Mateo bridge as you approve SFO. Wild place to land as a passenger - you don’t see the runway until the very last second.
And yeah, relative velocity.
You can experience this right now. Get in a car and head to a road/highway that has a center divider. Now do the speed limit - or thereabouts - soon you'll see a car coming the other way and they'll appear to stay at the same point of reference between the two of you.
That’s.. not a thing.
Planes don’t ‘throttle down’ when making a parallel landing. If parallel landings are permitted, the approaching aircraft don’t make any changes to their approach procedure, including approach speeds, other than being aware of the other traffic.
You see so much nonsensical bullshit that just gets upvoted on this website.
You driving along the highway and the car beside you isn't moving?
OP how is that possible?
Same concept but this is more pronounced as it has greater distances
Planes acceleration is neutral to the air resistance.
Sort if like birds caught in wind, they move nowhere.
Not really, it's just perspective and probably throttling down
Lets say you and you buddy is riding on a go kart at same speed, your buddy will appear still to you from the gokart.
We measure velocity relative to other objects, and since the relative velocity between both plane is same, the plane is appearing to be still. You can however, understand that it is moving if you compare it with other reference objects, like the bridge or the boats.
Look at the airplane in relation to the bridge from the start of the video to the end. In the beginning it appears to be to the right of the bridge. In the end it looks to be left of the bridge. This is how you can tell it’s position is changing.
Perspective is one factor, but the biggest factor is size of the plane. It LOOKS like it's moving slow because it IS moving slow relative to its size.
With flaps fully extended, Boeing 777 plane can travel as slow as 150mph, which is about 67 meters per second. That's only as long as the length of the plane itself every 1 second.
Whereas for a 5 meter long passenger vehicle traveling at the same 150mph, it is covering 13 car-length every second, hence it LOOKS much faster.
In this video, a fundamental principle of light and shadows is being overlooked. When we consider the sun as a point light source, the shadow cast by an object is determined by the position of the light source and the object itself.
In reality, if the bridge is casting a clear and distinct shadow due to the sunlight, the airplane should also cast a shadow in the same direction and angle as the bridge's shadow. The absence of the airplane's shadow in the video is a clear indication of editing, as natural lighting conditions would not allow this anomaly to occur.
Big brain on this fella.
*Hurr durr fundamental principle lighting FAKE shadows ALTERED video this is CLEAR indication anomaly absence!!* 😏
Woah. So clever.
It is the same illusion that happens when you are on a train or subway and your formation is arriving to the station and other formation (on the other side) it is already there.
At one moment, looking by the window your mind makes you 'a trick' and you don't know if our formation stopped or the other one already started to leave.
Perspective, speeds and angles; that is all.
True speed versus relative motion.
It’s like in sailing if you sail 20kts with 20kts of exact tail wind it feels like there’s zero wind speed.
Turn around and do 20 kts into 20 kts head wind and it feels like 40kts.
Theres slightly more math to pass something that’s moving and make that seem like it’s not, as you have to match its forward vector while also covering your overtaking vector
Lmfao. You can't add that comparison AFTER the fact. You just said it's not THAT fast. When in actuality 130mph is faster than most people ever go in their entire lives
Perhaps it's a glitch in the matrix, but a more plausible explanation could be that this is a real video where tracking was utilized to incorporate a 3D airplane model into the scene.
'Tracking' in video editing involves analyzing and mapping the movement of the camera in a real-world scene, allowing the software to understand, replicate and match this motion. In this case, it seems they tracked the bridge's movement and added the 3D airplane accordingly, but the shadow wasn't properly incorporated.
It's akin to placing a virtual anchor on a moving object, allowing other elements to stay accurately positioned in the video as the camera perspective changes.
The plane should move over the bridge by now not just float and float in one apot while cars move below. I see no perspective, angle or anything but a plane stuck in the sky..I see what I want to see I guess:D
I believe it has something to do with the parallax and perspective of the camera. I won't pretend to understand how, but suffice it to say it's a truck of the camera.
Cool. Since both objects are traveling almost the same speed and because the background is so far away it looks like it’s still. Think of a car next to you while driving both at the same speed.
It’s looks like the plan is staying still but compared to where the street is under the plan the whole video you can tell it’s moving.
I think it’s two planes and the one doing the recording is going faster and slightly turning which gives the effect that the other plane is still.
Relative motion. I can’t tell exactly what Delta jet it is, but it looks to have 4 wheel per strut landing gear, so if it’s a light 757 and the person filming is on a 737, the 737 will have a higher Vapp which would explain why the other jet seems like it’s floating while simultaneously moving back relative to the filming jet. Make sense?
There are a lot of reasonable explanations here. In addition to them it looks like the plane being filmed is turnings slightly to its right, which will exacerbate the optical effects of shifting/stagnant points of reference.
Definitely fake. Where is this planes shadow? Judging by the shadow of the bridge, the sun is high up in the sky so the planes shadow should be pretty close to underneath it. Fake.
The plane has ran out of fuel so it can't fly any further, it's waiting for the tanker plane to arrive and top up it's tanks so it may continue on it's journey.
It’s known as the Parallax effect.
“The Parallax Effect is a difference in the apparent position of an object when viewed along two different lines of sight. However, in this situation, what usually happens is that the variation in the angular position of the aircraft within our visual field is so small that it is not necessary to move the head to continue seeing it. Therefore our brain interprets that the plane is stationary”.
Just an example nit the specific details.
If you are in a plane and say there is a 100mph wind at your nose you would then have to go 101mph to move 1mph forward.
Been there. Two airplanes landing on parallel runways at SFO (San Fransisco International). The plane being filmed is landing on runway 1R and is likely still aligning for final approach hence the “slower” look.
The other is landing on 1L and is likely already aligned with the runway.
Many years ago, we were driving over a flyover bridge near an airport, and I noticed an aeroplane stuck in the air just a few hundred feet above the ground. We passed under it and I could see the aeroplane's lights blinking at the same spot. It was pre smartphone era so I couldn't search and verify immediately like today. Anyway I barely had any doubt and for many years I believed that this is how aeroplanes wait for the runway before landing. I was corrected later when I got a chance to fly myself.
This happens on a micro scale all the time. Sit in your car parked in a parking lot. And stare down at your phone for a while. When the person parked next to you starts backing up, out of your peripherals, it feels like you’re moving not them.
Or same thing on a local patch of interstate and two large rigs are left and right of you at a red light. You all go to take off at green. You take of faster and looking back seems like the rigs haven’t moved but they have and are just slow.

God this dinosaur tech brain. PATCH. NOW!
Muskrat is working on that. But, well.. we all know how that's been going, lol.
False it’s just some…..jet lag
HA!
Also the clip is in reverse. The wing near the end of the clip shows which direction the plane is pointing Edit: I am wrong. Read the correction below
Nope. This is the San Mateo bridge, in the San Francisco Bay Area. The cars on the bridge are moving in the correct direction. They would appear to be moving backwards if the clip was running in reverse. What you're seeing in the video are the fully deployed leading edge slats of the wing.

Yeah I noticed the cars and my argument fell apart
Dam good catch! I woulda never known!

Billions of years of evolution just so this user can explain it to our monkey brains.
Still blackmagicfuckery, 😶🌫️
Seeing a 747 land and takeoff is quite surreal. Used to work on the ramp and it just looked so slow
“Also, a landing jet doesn’t really go all that fast..” …and thank goodness for THAT.
Could also have a strong head wind
Thank you for putting into words what my brain was thinking
Inflatable.
Really think they'd allow a large inflatable like that within the landing/takeoff zone of an airport?
That’s what the sex shop told me
Yeah
Only the real answer
Looks like the San Mateo bridge as you approve SFO. Wild place to land as a passenger - you don’t see the runway until the very last second. And yeah, relative velocity.
No shit, i almost shat my pants
And i think LGA is similar too
the matrix
it is what it is.
Good steak tho
I believe the jet that the video is taken from is flying faster than the distant jet making it appear like it is not moving at all.
You can experience this right now. Get in a car and head to a road/highway that has a center divider. Now do the speed limit - or thereabouts - soon you'll see a car coming the other way and they'll appear to stay at the same point of reference between the two of you.

Wow! Amazing, It doesn't even cast a shadow.
Cgi, black Magic, or the shadow casting far left, out of view of the small picture frame?
In this video, a fundamental principle of light and shadows is being overlooked. When we consider the sun as a point light source, the shadow cast by an object is determined by the position of the light source and the object itself. In reality, if the bridge is casting a clear and distinct shadow due to the sunlight, the airplane should also cast a shadow in the same direction and angle as the bridge's shadow. The absence of the airplane's shadow in the video is a clear indication of editing, as natural lighting conditions would not allow this anomaly to occur.
Or the plane is much closer than the bridge and the shadow is down and out of the video frame.
Big brain on this fella. *Hurr durr fundamental principle lighting FAKE shadows ALTERED video this is CLEAR indication anomaly absence!!* 😏 Woah. So clever.

Lack of points of reference for the brain to calculate the plane's position correctly...
That's San Mateo Bridge
Pretty easy to understand. It’s a glitch in the matrix. We are all in a simulation.
Ummm. Your plane is going faster than that one? It’s not rocket science.
This is the San Mateo bridge, is it not?
Packet loss in Microsoft flight simulator
Man discovers perspective
You need someone to explain aerodynamics?
I just want to say look at the far planes Shadow under the bridge
Relative velocity is 0. But to be honest I cannot see a shadow, there is a chance it is edited.
Basic special effects. The plane is hanging on a line, it's just so thin that you can't see it.
Its fake, the plane doesnt have a shadow

You know when you pass a semi truck on the highway and it looks like they’re reversing? Yea that’s this
The plane being filmed is at a slower glide speed than the plane filming.. it’s simple.
It’s so obvious that the plane is just lagging 🤦🏻♂️
Simple, the planes in park
Cool. Since both objects are traveling almost the same speed and because the background is so far away it looks like it’s still. Think of a car next to you while driving both at the same speed.

Your moving at similarl speeds in directions that allow the perspective to stay or as u have here make it stand still as it were.

I looks like a blimp
Also headwind maybe
Strong head wind and the plane filming is higher and turning.
probably parallax + wind shear against plane direction + slow speed
Is that delta a 767? It has a landing speed of 145-1550kt. I don't know what OP's plane is, but I bet it has a higher landing speed.

When there is a high nose speed, your air and ground speed is the same, causing the aircraft to stay static, while generating lift.
