I hadn't seen this thread but I'm not buying it. The scanner buffs around here had all the frequencies except the scrambled stuff up, and unless all of this negotiation was happening on one of those... Nah.
Nauga is right on this one. There'd be posts about folks hearing the fuel emergency call even if it was just part of the post-"knock it off" call on the team frequency.
It took the scanner folks about two hours to have every single primary and backup frequency for the forest fire stuff figured out today after the handoff to the USFS team, for example. Not just the usual stuff but even the handhelds at the tanker bases, and what not.
That info gets around lightning fast. At air shows about half to three quarters of it is guessed at before the show even begins.
POTUS' freqs? A little less known. Well usually known very well and fairly quickly but uncopyable encrypted P-25.
