One other thing I noticed that I didn't like, is that if Unicom jumped in to let traffic know there had been 'two at once' they would often then tell one of the a/c to go ahead first
As the ground bit of an air-ground network, if you hear the squealie noise of two-in-together, and just announce "two in together", in the majority of occasions it is followed by another sqealie noise. If you can pick anything out of one of the transmissions (hopefully the first to start) you tell THAT one to go ahead, or standby if you think it is a radio check. It seems rather touching that pilots over there have an interest in whether their radios work or not, nobody here seems to give a bugger
