Yesterday the Transport Minister mentioned that they had received further radar data but that he was not at liberty to discuss it any further. IIRC a journo asked a question about that point, and the Transport Minister just repeated himself, and then added that 'also you have to understand that this data can be sensitive to the countries involved'. Does anybody have any theories as to where this data could be from? It was not mentioned by the TM today IIRC.
Most likely this data was shared by India. They dont want to reveal capabilities of their Andaman radar. If you notice India was quick to suspend the search in Bay of Bengal on 15th March, once they reviewed their radar tapes. Inside info from Indian Naval command is that India provided significant amount of radar data to Malaysia on 15th or 16th March. The other country could be Australia.
These countries do want to be anonymous due to several known reasons.
