go to a series of waypoints. was that all programmed into the computer which would have said someone was at the controls and deliberately took that course? in any company there's a problem with connectivity. here you're looking at malaysian radar, chinese radar and the various pings. i think the family is right. they have to be more forthright with coming out with this data. if you take a circle route it's going to be a straight line. if it was on a magnetic heading it's going to be on more of a hunt and seek line, curved line. that's going to tell us more about what went into the's. i don't think we're being told enough and i don't think the families are being told enough to figure out. if this data had been made available weeks ago i think there are lots of smart people around the world, lots of big data analyst who could have looked at this and come up with fresh theories much more earlier
