could be but 7800 would be impossible. Transponder codes are octal.
Haha well played.
As for the topic of the thread, perhaps someone with more international knowledge than I can clear something up. The only time an a/c should ever squack 7700 would be if they are unidentified to ATC or also have a subsequent radio failure...
Planes (especially jets) in the US dont just squack 7700 when they declare an emergency and ATC does not request they do, they maintain their discrete beacon code.
Is this different internationally? Thats the part I find interesting about the story...
