23 days since the mysterious disappearance of Malaysia Airlines Flight MH370 along with its 227 passengers and 12 crew members, the search continues for the missing Malaysian airliner, using just about every tool available to narrow down the possible locations where the Boeing 777-200ER could have went down.

While satellites have been able to capture imagery of the designated search area in the southern Indian Ocean where Flight MH370 is believed to have gone down, the International search team has relied on various tools to take a closer look, both low-tech and high-tech to aid in their search.

In the air, Lockheed P-3 Orions, Ilyushin IL-76s, Boeing P-8 Poseidons, Lockheed C-130s and various helicopters have been scouring the sea from above, looking for any sign of wreckage from Flight MH370. While these various aircraft contain radar equipment and other tools to aid in the search for the missing Malaysia Airlines flight, the crew on board have also relied on less sophisticated methods to spot any sign of Flight 370. Using binoculars, plain sight and digital cameras, crewmembers have been constantly looking out of plane windows, hoping to discover any leads on the disappearance of Flight MH370.

While several debris pieces were found in recent days, the airplanes flying overhead had to rely on other methods to retrieve anything spotted in the water.This was achieved by dropping GPS locator buoys or other signaling devices, so ships below can later retrieve the debris pieces and determine if they were related to Flight MH370.

In the sea, ships relied on various methods to aid in the search for Malaysia Airlines Flight MH370. While some ships have been used to retrieve pieces of debris spotted by planes, others have been tasked with the role of searching below sea level, in hopes of locating the flight data recorder, commonly known as the black box.

A combination of sophisticated sensors such as a towed pinger locator and underwater mapping robots deployed on Sunday to aid with the underwater search for Flight MH370. Search teams hope to narrow down the search for the black box, whose battery is estimated to have a life of about 30 days.

Even with the narrow window to locate the black box, search efforts continue to find any sign of Flight 370.
