they're talking about broadening out the search area now. i wanted to chat a little bit about that object of interest that we discussed yesterday that was found off the coast of western australia, about 190 miles from here. authorities have since ruled it out as being connected to mh370. cnn has managed to obtain photos of that object. looking at them, it is easy to see why authorities are so interested in this piece of long metal with rivets. in the end it turned out to be just another lead transformed into disappointment. meanwhile mh370, the search continues. they're talking about introducing more powerful under water submersibles. the bluefin-21's mission nearly complete. scouring the targeted search area with a six-mile radius where investigators say flight 370 would have likely crashed.
