There is a well-known technology of deploying underwater acoustic sensors from aircraft to listen to sounds below the ocean. Visit

The military forces of about a dozen nations are involved in the search for the blackboxes of Malaysian Airlines MH 370. Why is no one talking about deploying some sonobuoys, before it is too late?

ReplyDeleteThey have finally used sonobuoys and got some useful information on the location of the black-boxes of MH370. Visit

Why didn’t they do this earlier? I believe that they cannot use sonobuoys to search a large area. Pings don’t travel very far underwater, and it would take a lot of sonobuoys to cover a good piece of the ocean! You drop them when you have a good clue about the approximate place where the pings can be heard. In other words, they are useful to search for a needle in the haystack, but they are no good for finding the haystack itself!
