What a frightening story. You have to fear the worst, when you read:
Mr Borloo, the minister in charge of transport, said the plane would already have run out of fuel.

Maybe airlines should have numerous small cheap floating transponders attached to life jackets, seats, and anything else that may float after a sea crash. They could bleep with a code that identifies the aircraft. The drift of a mass of trasponders may help locate where the crash happened and which direction the ocean currents are carrying any surviviors.

I just assumed that with radar, GPS etc they would have a pretty good idea where the things were. A also assumed that the black box would contain some sort of location device?

Not one that can be picked up in a search area of hundreds of square miles transmitting from the bottom of the sea.

Radar can only 'see' in line of sight. Once the curvature of the earth kicks in, you start to lose visibility. It is one of the reason why the military put up airborne radar to allow it see over the horizon. Covering the oceans is impossible and aircraft must fly on agreed routes and follow strict procedures when crossing oceans. GPS will allow the aircraft to know where it is and messages are being continually transmitted from the aircraft, but it is not completely foolproof or up to date.

My thoughts were sort of along the lines of the plastic ducks. A few years ago a shipping container fell off a cargo ship and spilt it's load of yellow plastic ducks. Scientists and climateologists have been plotting the course of the plastic ducks ever since to learn about oceanic currents.

Thousands of little transponders may give off just enough of a signal en-mass just after a crash to hlep a quick rescue. If not then once they spread out there may be more chance of a detection over a wider area. Knowledge of the ocean currents could help track where they all came from at the time of the crash.
