自從馬航客機失聯之後，馬來西亞政府、軍方和馬航當局，一再發布模糊不清的資訊，這些資訊又往往前後矛盾、彼此否定，令人撲朔迷離。初期，一會兒說失聯地點在馬來西亞和越南之間海域，一會兒說不對，飛機已經折返飛向西邊；過了一段時間，又傳出新的版本，說飛機可能沿著往西和往南的兩個飛行走廊繼續飛行，去向不明……總之，莫衷一是。. Q$ @- H) x# W  Y7 y) `. c

根據馬來西亞政府先後歷次發布的資訊，其中表明馬航失聯的MH370客機曾經一度橫跨馬來西亞半島。然而，馬來西亞方面，不論是政府、軍方還是馬航當局，都至今沒有說明，為何跨境飛越馬來西亞半島時，馬來西亞為何不能及時及時提供失聯客機蹤跡的資訊？否則，如果各國當時及時採取一些必要的適當措施，也許足以改變目前的狀況。

很顯然，「羊毛出在羊身上」，如果馬航，或者馬來西亞政府能夠持續地支付相關協作費用，這種「大合唱」式的聯手合作勢必將繼續下去。越南在馬航迷蹤初期不但積極投身參與搜尋，還大方開放領海領空接受各國艦船前往搜尋，但是隨後不久即和日本等國鳴金收兵，不排除在馬來西亞支付經費方面出現「斷糧」現象。

馬航迷蹤超過半個月，凶多吉少是預想中的事。然而，一旦未能拿出確鑿有力的證據，都難以給這宗離奇案件打上句號。目前，美軍已經把黑匣子定位器以及水下航行器送往珀斯，幫助搜尋失聯馬航的黑匣子。人們既期待馬來西亞政府後續提供的馬航迷蹤資訊有助於繼續搜尋，更冀望於及早搜尋到失聯馬航的黑匣子，儘快破解馬航失聯真相。

If the ground station has not heard from an aircraft for an hour it will transmit a 'log on / log off' message, sometimes referred to as a ‘ping’, using the aircraft’s unique identifier.

In recent days Inmarsat developed a second innovative technique which considers the velocity of the aircraft relative to the satellite. Depending on this relative movement, the frequency received and transmitted will differ from its normal value, in much the same way that the sound of a passing car changes as it approaches and passes by. This is called the Doppler effect. The Inmarsat technique analyses the difference between the frequency that the ground station expects to receive and that actually measured. This difference is the result of the Doppler effect and is known as the Burst Frequency Offset.

In order to establish confidence in its theory, Inmarsat checked its predictions using information obtained from six other B777 aircraft flying on the same day in various directions. There was good agreement.

While on the ground at Kuala Lumpur airport, and during the early stage of the flight, MH370 transmitted several messages.

During the flight the ground station logged the transmitted and received pulse frequencies at each handshake.

The analysis showed poor correlation with the Northern corridor, but good correlation with the Southern corridor, and depending on the ground speed of the aircraft it was then possible to estimate positions at 0011 UTC, at which the last complete handshake took place.
