A Frantic last message to Malaysian Flight MH370 Was Hidden From The Public Until Now

Malaysia's Ministry of Transport has this week released the full log of communication betweenMalaysian Flight MH370  and the ground.
Authorities had been accused of releasing incomplete and edited logs.The new log contains an additional message that was sent from MAS Operations Dispatch Center (ODC) and destined for MH370.
It was sent around the time of the first unanswered phone call to the pilot Captain Zaharie Ahmad Shah.
The message was sent at 18:38:51 and was intended to be displayed in the cockpit on a Control Display Unit (CDU).

The message was not received by the plane, and was re-sent at 18:39:52, 18:40:42, and 18:41:52, failing each time.
The text of the message was:

 “DEAR MH370. PLS ACK TEST MSG. RGDS/OC.”
