Air France Flight 447 and the current status of technology

I think, as of today, the world doesn’t know the final status of Air France Flight 447. We still don’t know what happened to that flight nor we do we know if there are any survivals.

I am not a pilot, although I did some flying in the past, I don’t know exactly how the GPS system works or other localizers inside the plan (such as the transponder.) But I know that our current technology should be good enough to give us the location of the airplane at any moment. There are hundreds of satellites that span the globe, thousands of airplanes flying our airspace and navies of few countries are all involved in the search for this airplane, but still no clue.

It’s hard to believe with all these technology and resources at our disposal and we still not able to locate this one airplane. This reminds me of the weapon of Mass destructions which were never found.
