Field. one has already picked up four pings from the towed pinger locator. they drop a line down from a thousand feet and listen basically. it seems one of them got a hit, a ping from the frequency hit from the data recorder. that has given even more optimism to those searches. preliminary data, though -- >> let's talk about that preliminary data. i understand the testing was done overnight to try to analyze if the signal came from flight 370. do we know when we'll get an update on that, or when the process is? >> well, yeah, hopefully today. you're right. the plane gets the signal back from t...
