I think what you have here is two photo’s taken a couple of seconds apart superimposed on each other. Take a look at the traffic on the highway to the south. Many of the vehicles are duplicated at about the same interval.

So the Ryan Air 737 is the same plane twice.

Then why are some vehicles duplicated on the route below, and some are not?

I’m certainly not discrediting what you said, Google earth is certainly a mosaic of pictures taken over time. If we look VERY carefully, we can sometimes see a slightly blurry area, the “scar” between 2 images. (I looked attentively around the 2 737’s, but did not see any.

I could be right, I could be wrong, but I have a tendency to think that there may have been 2 737’s a couple of hundred feet apart, taxiing and following the same yellow line.

Check your theory against Needlenose’s image reference above.

In the GE overlay at Stansted there are what appears to be 6 Ryanair 737s on the runway and taxiways. As 23 appears to be the active runway, there’s no way the “two” aircraft shown at 51 52’55.60N 0 13’ 50.27E are anything but either the same aircraft or similar aircraft images taken at different times.

Needlenose’s image reference near LaGuardia is definitely, withouth the shadow of a doubt, result of imagery juxtaposition.

I just have a little reserve of the Stanstead theory based on the fact that those imagery satellites orbit around the earth in approximately 90 minutes.
That means that in the lapse of time that the 737 would advance a few hundred feet, the satellite would already be filming a few hundred miles past that point.

Unless…

-There is more than one imaging satellite;
-There is more than one camera oriented differently on the sat;
-The satellite passed, say the next day, and that another (or the same) 737 happened to be in approximately the same location on the runway
(This could be the LaGuardia scenario).

…or purpose of the original sat. photos were to create a stereoscopic image. Pictures ’ snapped ’ 0.5 / 3 sec. sec apart from satellite would do the job. Though GE is a wonderful treasure trove of satellite images, all the images were created for other purposes in mind ( either gov’t or private interest ).

As well, I don’t think a ground controller would allow two 737’s to exit a runway at such close proximity to each other.

The high detail images are from aircraft, not satellites.

Most people are surprised to learn that we have more than one source for our imagery. We collect it via airplane and satellite, but also just about any way you can imagine getting a camera above the Earth’s surface: hot air balloons, model airplanes even kites. The traditional aerial survey involves mounting a special gyroscopic, stabilized camera in the belly of an airplane and flying it at an elevation of between 15,000 feet and 30,000 feet, depending on the resolution of imagery you’re interested in. As the plane takes a predefined route over the desired area, it forms a series of parallel lines with about 40 percent overlap between lines and 60 percent overlap in the direction of flight. This overlap of images is what provides us with enough detail to remove distortions caused by the varying shape of the Earth’s surface.

I agree, it is a bit close for 2 taxiing aircraft.

I assumed satellite coverage because the pictures were provided by DigtalGlobe. Didn’t realize they used aerial photography as well.
