signals off if it were to have ended up in the water? >> it would, because it's just like a radio, it's a transmitter, if it crashed on land it would transmit that signal unless that antenna got broken off. if it goes in the water, once it hits the water, it grounds out and it can't transmit. >> so les, to you, it seems odd that the technology meant to signal in an emergency would stop working if it hits water at all? >> well i'm not so sure -- if it hits water and immersed right away yes, that would be the case which may have occurred with mh-370 because of the elts, the emergency locater transmitters were located in the rafts that were probably never utilized. but, they also activate upon impact. and it depends on the g force they impact with. >> okay yeah. still so many questions, again, don't want to make assumptions because we do not know what happened tim, talk to me about
