To recap the main points from that press conference:
25 countries are now involved in the search effort, which is now focused on large tracts of land covering 11 countries, and deep stretches of sea.
It was confirmed police have searched the homes of the pilot and co-pilot - removing a flight simulator from the pilot's house - but the two men did not ask to fly together on flight MH370.
The plane did not take off with any additional fuel on board, other than what would be needed for a normal flight.
It is possible that the last satellite signal received from the plane was sent when the plane was on the ground.
Authorities do not believe there was any hazardous cargo on board.
The plane's ACARS transmission system was switched off before the plane's last communication with ground control.
