the first technology of its kind. mom and dad, i have great news. is now providing answers families need. siemens. answers. humans even when we cross our t s and dot our i s, we still run into problems. that s why liberty mutual insurance
work. that s one of the biggest problems in this search. the plane s transponder and the a car system that sends back data about the plane s health were apparently switched off. wouldn t surprise me that in the aftermath of this investigati investigation, a safety recommendation comes from the ntsb in this country, say you just have to put on a tracking system in every airliner that cannot be disabled. another piece of technology that could be due for an upgrade, flight data recorders. their batteries are only required to last 30 days and the signals they send have a range of only about two miles, making them difficult to find unless search teams are close by and lu lucky. let s talk a little more about the complications of upgrading these planes. and the cost. with andrew thomas, the founding editor in chief for the journal of transportation, security and
happened here in new york city in the days after 9/11. this is a good one. yesterday folks gathered at that same shopping mall, sort of interfaith event, sending their prayers to the people aboard flight 370. so lots of tributes being paid. as for the ongoing investigation, there s now talk about special tracking technology that could have potentially given the officials on the ground more information if the missing jet had had it on board. dan springer with details of that, he s live in seattle. how is this thing supposed to work? yeah, shep, who knew? think of it as a constant streaming of all the information held in an aircraft s black box to a controller on the ground. that would tell the airline about all the important airline functions and the plane s gps location within a few feet. the system is made by a company in canada and it s already installed, get this, on 350 planes owned by 40 different carriers. it works even when the plane has lost power or the other
communications systems have been turned off. the idea behind it was to allow airlines to be more efficient by quickly identifying mechanical problems. but as an added bonus, it would mean never having to hunt for a missing airplane again. there s literally no further investment in infrastructure that would be required to do this. obviously more s better, but the infrastructure in place now, which is the iridium constellation and the internet are the major pieces that you need to do this job. and the system costs just under $100,000 per plane. it is not required currently by the airline industry. but there is some tracking technology that s soon to be required, right? what s the store y with that. it s a transponder that will transmit to the world the exact location of all the plane. boeing is putting it on all its new planes. the feds require it by 2020.
behind bars because of the information in their pockets as they drive around. it s so specific. we can find out where people were in the middle of the night, in the middle of the desert, but we cannot find an airplane with all the technology that we have to track people, to track planes. what is wrong with this picture? the tracking technology, how is it so deficient? that story next.
