Note that recording name of imagery + rough date of it can be very useful in this context

Nice image.
Airplanes in imagery are a fairly common sight especially around large and much frequented airports of course. They tell you quite a lot of thing on how the image was taken. The one you showed was for example photographed by a satellite with a higher resolution panchromatic band and significantly lower resolution multispectral sensor with a linear resolution ratio of about 1:4 as typical for today’s commercial high resolution satellites. This manifests in the sharp but colorless plane and several slightly offset blurred images of it in different colors.
For comparison here a typical image of a plane in lower resolution imagery without a separate panchromatic band:

Yes, it happened one previously found appears no more in recent image.
Thank you both for the infos, I’ve improved the map.
If you see other planes, feel free to ad it to the map!
