Caught a news item this evening where they noted that RADAR (at least civilian RADAR) is generally only good to 120 miles or so... and aside from ship-board military systems, once a plane gets over water more than that distance from shore, it does essentially vanish from RADAR tracking and must rely on GPS tracking and radio or satellite position reporting to the tracking systems.
