Wondering why Malaysia Airlines Flight MH370 is still missing. The Federal government recently created and posted a video on YouTube containing answers to the question. Scroll down to watch the video.

Even after nine months of its disappearance and multinational search efforts, MH370 has not been found and has become one of the greatest mysteries of aviation history. In an attempt to update the families of the passengers of missing Malaysia Airlines jet, the organisation dedicated to the hunt of the plane, Joint Agency Coordination Centre has posted a video on YouTube.com that explains why they have not been able to locate the aircraft yet. Daily Mail reports that it explains why the investigators continue to concentrate their search mission "along the seventh arc in the southern Indian Ocean." It is the area in the ocean that hosts harsh conditions and very deep water.

Malaysia Airlines flight MH370 went missing on March 8, 2014 with 239 people, belonging to 15 different nations. The plane was travelling from Kuala Lumpur to Beijing with six Australians in it. The plane went off the radar just few minutes after its take off from the Malaysian airport. Since then the plane has been missing. Meanwhile, based on satellite data, on March 24, 2014, the Malaysian government declared that the missing MH370 "ended in Indian Ocean."

Earlier in November, a report surfaced claiming that a representative allegedly announced that Malaysia Airlines flight MH370 will be declared "lost" by the end of the year. According to Express UK, alleged comments by Commercial Director Hugh Dunleavy infuriated the families of the passengers. Later, JACC assured that despite the comments the hunt for the plane will continue.

Daily Mail notes that the video addresses the same issue that caused much agony among the passengers' kin. "The expert satellite working group is continually refining analysis of the available data to identify the areas of the highest priority for the search" states the video.

The three-minute and 54-second long video attempts to explain that the plane is possibly in a "remote" area of the vast ocean with water as deep as 6km. The authorities are currently examining the seafloor and the waves -- the knowledge of which can assist them further in the search. It is explained that the depth of the water does not allow daylight to penetrate in all the areas of the ocean. The deep regions reportedly lack sunlight, which makes it difficult for the investigators to carry out the search. The video also talks about the vessels deployed for the search mission including Fugro Discovery, Fugro Equator and GO Pheonix.

In its latest update, JACC revealed that the authorities have investigated over 6900 square kilometres of the Indian Ocean's seafloor so far. Meanwhile, Stuff.co.nz reports that experts have not "found a single piece of evidence of the plane." However, they have made some "fascinating undersea crevices and inactive volcano."
