While one report suggested that Flight MH370 may have flown across the Malay peninsula towards the Andaman Islands, another quoting a US official spoke about the possibility of the plane having flown far away from the areas currently searched jointly by 13 countries, including India.
Aviation experts discounted both possibilities, reasoning that the Boeing 777-200 could not have flown undetected over such a long distance.
The request from Malaysia came a day after India joined the massive search operations by deploying six aircraft including its latest special surveillance P-8I plane and three helicopters under 'Operation Searchlight'.
India's navy, air force and coast guard are searching for the MH370 flight in the south Andaman Sea following a request from Malaysia.
