I still frequently hear SAS being called several times on the frequencies. Apparently they did not learn from this occurance.
German ATC recently avoided pressing the huge red button, by calling the airline and asked them to send an ACARS message to a flight that lost communication.
I was once called on 121.5 only a few minutes after checking in on a frequency and getting "indentified". We never got a proper explanation, other than we were out of the other sector. We never got a frequency change from the sector we left.
I find it strange that in the UK you think you should use the emergency frequency for training calls. Imagine if that was practice all over Europe!
