i've talked to a lot of pilots, they say yes. they have seen the shadow theory work, in fact, with other people, bad people trying to keep either drug planes away from other planes or whatever. if you get the planes close enough together, they will show up as one spot on the radar. and if you get a secondary radar, it squawks sq-68, not 370, because the transponder's turned off, and it doesn't even see 370, because with the transponder off, there is no proximity alert to this plane. doesn't work that way. if this is turned off, that plane doesn't even know it, and if it came up from behind or from the back, you may not even see the plane ever there. >> fascinating. >> absolutely. >> we'll get the very latest on the search for this flight right after a break. ♪
