Has this Google Maps imagery of 4 planes on a runway been tampered with?
Google Maps and Google Earth are made by stitching together many different images to create the illusion of a single massive picture of the globe.

The image you are seeing was almost certainly made by an aerial photography plane passing overhead of another plane landing.  In multiple snapshots, it captured the same plane on final, touching down, rolling out and stopping.

The images were assembled together to line up the ground and all static elements.  But items that are moving appear multiple times in different images.
