Largest Bluefin ever caught! World Record?!

Bluefin-21 search for Flight MH370
A robotic submarine has completed its first successful scan of the seabed in the hunt for the missing Malaysian plane, but investigators say tests have ruled out that a nearby oil slick came from the aircraft.

The Bluefin-21’s first two missions were cut short by technical problems and deep water, but the unmanned submarine managed to complete a full 16-hour scan of the seabed far off Australia’s west coast overnight. Data was still being analysed but nothing of note had yet been discovered. The sub has now scanned 90 sq km (35 sq miles) of the Indian Ocean floor.
