I am seriously keeping up and really worried about the missing plane. My worry is not only about the passengers but also the relatives in waiting.
Helicopters, planes and boats are launched with the hope of locating it. However, they can't see what is in the bottom of the sea. I have not read or heard that submarines are utilized in the search. Why not? They may have been used by now, but, I just did not read about it anywhere.
