the future? here s tech correspondent lawrie seagull. reporter: the story of what went wrong vanished. the answers could be in the black box. what if we had those answers all along? we would know where the aircraft has gone, where it is, and we would have information on what happened in the meantime. reporter: flight makes live streaming data recorders that send information in realtime. it s part of a satellite-based system that monitors the exact location, engine conditions and more. the system transmits every five to ten minutes on a normal flight. reporter: if something goes wrong like the plane deviating from the route, it streams data. that kind of information is not only life saving, but it adds a tremendous measure of security for our country. reporter: there are several mechanisms that transmit data, but unlike the systems, the
the plane deviating from its route, it will start streaming live second by second data. that. that kind of information is not only life saving but lends tremendous security for our country. unlike those systems, the technology behind flight is more intensive, sharing a tremendous amount of information. it can be difficult to monitor and analyze. it is only fitted today to 350 planes. installed for about $100,000. normal data transmission cost carries between a few dollars to $15 per flight hour and goes up for continuous streaming in a rare emergency. they are very cost sensitive. they will not add additional safety measures unless mandated by the federal government z as they look for high-tech includes, the high-tech data recorder is getting a second look. the technology exists, it is
