Disappeared off the radar

An Ethiopian Airlines plane with 90 people on board crashed into the sea shortly after taking off from Beirut in stormy weather early on Monday and the airline's chief executive said there was no word of survivors.
The Boeing 737-800, heading for Addis Ababa, disappeared off the radar some five minutes after taking off at 2:37 a.m. (0037 GMT) during a thunder storm and heavy rain. Lebanese President Michel Suleiman said he did not think the plane had been brought down deliberately.

Could you please explain to me what "off the radar" means here?

The airlines, weather reporters, military, and others all have radar systems which track the things that interest them. If a planes falls/disappears off the radar, it isn't being registered by a "blip" when the tracer goes around.
