I was tracking an over-flight KAL902. When I clicked on the plane I got a picture of a Korean Airlines 747. I looked for KAL902 on the flightstatus web site and it gave me KA902 which was a Dragonair flight. I then typed in Korean to the flightstatus site and that gave a prefix of KE. And flight KE902 was a flight from Charles de Gaulle to Inchen (which was quite likely looking at the height and direction on the display).
Any explanation please?
Regards Mike
PS Still a fantastic sight! Better viewing than the tele
