The search for flight MH370 enters day three, today.

Authorities late Sunday night reported that there has been no sighting of the mysteriously missing Malaysia Airlines aircraft Boeing 700-200ER.

However, the Malaysian-led operation carries on with assistance by Vietnam, China, Singapore, Indonesia, Thailand, United States, Philippines, and Australia.

With 34 aircrafts and 40 vessels from Operations the search has expanded from 20 nautical miles to 50 nautical miles, some 120 nautical miles east of Kota Baru.

Based on information provided by the Royal Malaysian Air Force chief Tan Sri Rodzali Daud, who stated of a possible turn back to the Kuala Lumpur International Airport (KLIA) as per radar records, the search has now been expended to include the West Coast Straits of Malacca.

As the round-the-clock search continues on Monday, here is a brief summary of what we know so far:
MH370 had 239 people on board from 14 nationalities. They included at least 152 Chinese, 38 Malaysians, seven Indonesians, six Australians, five Indians, four French and three Americans. These included two infants.

There were also five passengers who had purchased tickets bound for Beijing, but did not board. All baggages were removed.

The MAS flight went missing at 2.40am on a Kuala Lumpur to Beijing flight two hours after it took off at 12.41am on Saturday. It was scheduled to land in Beijing at 6.30 am. on Saturday.

MAS had said it was"fearing for the worst".
