Excellent idea for a subject to debate in another forum.
Suggest you do start it in "Airline, airports and routes"...
I will join in with my usual "old fart" ideas from last century.
Would be better there than under a label of "emergency frequencies".
Here, all that is suitable is mentions of Morse Code SOS.
Did did did, dah dah dah, did did did, was it...?
