Flight MH370 Search: Australian Officials Certain to Find Plane; Signals Declared 'Not of Natural Origin'

Search crews for the missing Malaysa Airlines Flight MH370 plane have detected two more signals that may relate to the black box of the aircraft. An Australian ship has heard the signas again on April 8.

According to officials, the signals or "pings" heard earlier were analyzed further by investigators and declared the signals came from "specific electronic equipment."

The Malaysia Airlines plane coming from Kuala Lumpur and bound for Beijing has disappeared on March 8 after ground control lost all communications with the plane carrying 239 people.

Malaysian executives concluded the plane went down in the southern Indian Ocean based on satellite data.

Ocean Shield, the Australian vessel carrying the pinger locator to find the signals from the plane's black box, believed to be in the waters off the coast of Perth. The ping locator has acquired the signals in the past weekend.

But signals were reacquired on April 8. During tThe first time, the signals were observed for 5 minutes and 32 seconds and 7 minutes for the second time.

Air Chief Marshall Angus Houston serves as the head of the joint coordination and search efforts said the Ocean Shield has detected four signals in the same area.

He added the recently acquired signals can help in arriving at a more manageable search area in the ocean.

Australian Joint Acoustic Analysis Center experts had analyzed the first two pings which were detected last weekend and results showed they came from a "clear signal."

Experts concluded the signals were "not of natural origin." This means the signals were possibly from a certain type of electronic equipment.

Houston said the experts believed the signals might be coming from the black box of Flight MH370.

One month of searching for the missing Malaysian plane has left the world baffled. The mysterious disappearance of the aircraft has given rise to several hoaxes and theories being shared in social media.

But Australian officials remain hopeful in finding the lost Flight MH370 and bringing closure to the families and relatives of its passengers and crew.

Australian Prime Minister Tony Abbott has promised to continue the search for the missing plane despite the growing challenges and costs of the international joint effort.

He assured the media Australia will keep on searching for any signs of Flight MH370 for "quite some time to come."
