JamesTK - I did read your post thoroughly and indeed have re-read it but this is what made me think you were saying that you thought that chatter on 121.5 out over the Atlantic was OK:
Occasionally, i hear airline guys/girls chatting on 121.5. I don't think it's professional when around busy UK airspace, but mid-altantic etc. ???.
It still reads as if that is what you think (at least that is the way it seems to me) so I'm sure you will understand my reaction to that idea. The information you supplied subsequently says that that isn't your meaning and I am very glad to hear it. I was very lucky and will always be very grateful to D&D and that Emirates pilot and also to the airfield FISO who followed all my calls even though unable to speak to or be heard by me.
