The quest for Malaysia Airlines Flight 370 has been restarted this week, with no trace of the aircraft since it went missing seven months back, post altering its course about eight hours later.

The search for the aircraft took off with the three ships scouring a distant area of the Indian Ocean which falls off the Western coast of Australia.

The flight took off from Kuala Lumpur for Beijing on March 8, with the aircraft's transponder signal and radio becoming silent in the initial hours of the flight.

In the meantime, the National Transportation Safety Board (NTSB) summoned in Washington with flying experts form all around the world participating in it deliberated upon improvising measures of tracking aircrafts while in the air and also on how to locate them when they crashed. Locating aircrafts that crash in the ocean is a more challenging task.

The most likely solutions to the problem of identifying ocean crash sites that the NTSB is pondering over entails the deployment of automatic dependent surveillance - broadcast (ADS-B),applied by the Malaysian aircraft also through which an aircraft's movement can be observed with the help of land-based radio towers.

The technique in a short span of time is expected to permit satellite tracking, which will enhance the coverage of open ocean waters.

Several other options which are being deliberated upon entail live streaming of cockpit as well as flight recorder statistics as a plane moves along its course.
