Check out the plane circled in red below. It has a very long track line. I wanted to get more information on the airplane to see
what might be causing this effect (maybe two airplanes with the same flight number), so I refreshed the display immediately
in an attempt to produce flight information on it… (next image)
Now there’s two tracks and the plane is in an unexpected position on the map (red dot indicates position in previous image)
Since no flight data appeared, I refreshed immediately again and the plane was gone! It just vanished… 
Based on the previous two images, I put a red dot in the location where you’d expect to see the plane.
Has anyone ever seen this phenomenon before? Any ideas as to the cause?
