Malaysia Airline System call sign is Malaysia. As rotuine the pilot contact Clearance Delivery then to the Ground Control to Aerodrome (Tower) Control to Kuala Lumpur Departure/Approach Centre. Kuala Lumpur Departure/Approach Control’s call sign is “Lumpur Approach.” Something is missing in the trascript. Lumpur Approach must had told MH370 to contact Subang Area Control Centre, supposedly the last contact. It’s not the job of Approach controllers to endrose the flight to Ho Chi Min ATC. I guess they’d need to tweak their supposedly ATC transcript.
So then what is the likelihood of the pilot using “Malaysia” as opposed to “Em Ach” and then releasing a transcript that has him saying “MH”???
