I was just wondering, how is it possible to find a tail number of the airplane in flight? The author of this photo claims that these two planes that have crashed are F-BTSC and SU-GAP. When I enlarged it on my screen, I could see that the concorde is indeed an F-BTSC, but how does he know that EgyptAir is SU-GAP. How is it possible?

Hope that someone could satisfy my curiousity.
