Given our great trust of the media maggots of late, are you sure that all of the audio is real?
Since when do ATC say: "Station calling Mayday say again" after hearing a well spoken Mayday call.
I thought the idea of saying MAYDAY MAYDAY MAYDAY was to prick up the ears of the ATC so he/she could take all of the information in, in one hit, without distracting the pilot from the emergency situation with a second request and then activate the emergency response and/or offer further operational information.
Condolences to the family of the pilot and good luck to the controller with her post-trauma counselling.
