After initially refusing to release the preliminary report on the disappearance of Malaysian Airlines flight 370 (callsign MH370), the Malaysian government has made it available to the public. In five pages, the report outlines the facts known about the history of the flight, the disappearance and search. It recounts details of the departure from Kuala Lumpur, climb to Flight Level 370, clearance directly to waypoint IGARI and conversations between the crew and Lumpur approach control and Lumpur "Radar" (analogous to "Center" in the U.S.). It states that Lumpur Radar handed off MH370 to Ho Chi Minh Center by directing the crew to contact it on frequency 120.9 at 01:19:24 Malaysian time. Lumpur Radar received the acknowledgment, "Good night Malaysian three seven zero." There was no further radio contact with the flight. Lumpur ATC radar depicted MH370 passing over IGARI at 01:21:04. Nine seconds later the radar label for MH370 disappeared from the radar screens at Lumpur Radar.
