Miami to Frankfurt flight path is a little strange… I’m guessing it’s a glitch?
2 flights in the air at the same time with the same flight number, usually a typo.
In this case, wouldn’t it be because you data from two different control centers at the same time? For example, at 19:42 there’s data from both Moncton and Gander. Ditto for 19:50.
I did not know the A380 went in to MIA.
