finding data on the flights, do you think part of that will be overall black boxes? >> this exposed huge gaps in our design of the airplane. first of all, the pilot should not be able to accidentally or deliberately disengage the radio transponder. perhaps one person, deliberately or accidentally disengaged all communications systems with ground control. they have to be anned in way of doing it other than the pings we're picking up and the transponder and data reporter, we have to make sure because of data compression, new technology makes it possible to track these airplanes without having to go into the grave yard of the ocean trying to get this black box. that's ridiculous. we have to make sure we have adequate data compression and satellite communication. we have up to the minute information as to what's happening with the airplane rather than waiting for it to go in. >> first let's talk about these transponder systems, why aren't
