I have to admit and I do not know if others experience the same but I feel really embarrassed saying "Mayday Mayday Mayday".
I remember with the smoke filled Citation incidence it had to be dragged out of me by the controller
My call started " Um we have a problem" Followed by the Controller asking the nature of the problem, then asking if I was declaring an emergency?
I don't know what it is with those words but I hate saying them!
would much prefer " XYZ is declaring a mayday" or even better " XYZ is declaring an emergency".
Maybe Mayday Mayday Mayday is to much like the films
