we have breaking news tonight, the air search for flight 370 has been suspended due to a tropical cyclone in the search area. back with my experts now, and they are answering your questions for you. first to michael kay. a question from joe nemo. if a suicide pilot's plan included mystifying the final fate of flight 370, wouldn't it make sense to disable the elts, too? that's a very good question. >> that is a good question. i'm not actually sure how you would disable the elts, but just for factual data, there are four beacons on the aircraft. there are two elts, emergency locator transmitters, in the nose and the tail. they are activated by g-loading, and then two sit in a compartment next to the emergency exit on a life raft and they are activated by salt water, i think there are lots of questions on why there weren't activations of the elts.
