I thingk Daily Mails wrong

Tracking Aircrat we do not use Radars (sic) (Daily mail can't spell [plural of Radar is Radar - no matter they're ignorant!).

Today we don't use Radar to track aircraft its done on computers using ADS-B

Basically the Plane says where it is using a "network" signal.

This has bee proved to be hackable and who knows what data the Air traffic control are "seeing" .

Hence disappearance of flight MH370.
