The search for Malaysia Airlines Flight 370

The search for a Malaysia Airlines flight that went missing on March 8 with 239 people aboard now involves 26 countries and an area slightly larger than the entire land mass of Australia.

Malaysia's government on Tuesday listed the countries and their ships or planes deployed in the so-called southern corridor, a vast 160,000 square nautical mile (550,000 square kilometre) area stretching from Indonesia to the southern Indian Ocean.

The government did not have details for the northern corridor -- stretching from Northern Thailand into central Asia -- where China and Kazakhstan are leading the search.

In the southern corridor:

-- Malaysia has deployed four ships, along with two Super Lynx helicopters, as well as two C-130 aircraft to the Indonesian sector of the corridor.

-- The United States has deployed one P-8 Poseidon patrol plane and will redeploy a P-3 Orion aircraft.

-- Australia has deployed three P-3 Orions and one C-130 Hercules.

-- New Zealand is redeploying a P-3 Orion to support Australian efforts.

-- South Korea has committed one P-3 Orion and one C-130 Hercules.

-- Japan has sent two P-3 Orions, two C-130s and one Gulfstream jet.

-- The United Arab Emirates has committed one C-17 aircraft and one Bombardier Dash-8 aircraft.

-- China has also made arrangements with Australia to deploy an aircraft to the southern corridor.
