I'm sorry but why in this day and age can we not find a brand new 738?

From a technology point of view it is quite easy to build a software that monitors transponder-activity and matches this with GPS localiser.
You are both basically correct but you have to accept that govrnments have to provide the on the ground infrastructure and, in the less developed parts of the world not only are they broke but a great deal of money that is donated for projects is syphoned off by individuals or into private armies.
In another post someone mentioned the fleet of the Cameroon Air Force. Looks good on paper but how many of those aircraft have trained pilots, how many are airworthy and how many can be usefully flown on an SAR mission?
Back to keeping track of aircraft. Have a look at ADS-B.htm" target=_blank>http://adsb.tc.faa.gov/ADS-B.htm
-B is already tracking thousands of aircraft, vehicles and ships cheaply and accurately. All computer download programmes record precisely the last position. The receiving station is a simple aerial (half or one metre) feeding a signal into a decoder, thence to a computer which displays a radar like picture. In underpopulated areas the signal can be relayed from the receiving decoder on another frequency to a central computer. Over oceans it can be sent from the aircraft via satellite, again to a simple aerial and decoder linked to a computer.
My own aerial/decoder/computer set up cost precisely €1300 (around $1766) and, from a base height of 5 ft AMSL on top of a 27 foot pole, pulls in signals without any booster, from up to 250 miles away over the ocean and up to 200 miles away over land from aircraft at heights down to FL130 or there abouts depending on mountains etc.
A series of aerials/decoders around any country would be cheap to install, could cover all areas and flight levels, have low maintenance and would have none of the cost/maintenance problems of radar.
Back to the KQ
crash. Last night's teatime (UK) BBC news had the crash site back at Niete - haven't heard anything different since. ITN talked of the 737-800 "shown here" as the camera panned along a KQ
777 - good old media, anything will do so long as we can fill the bulletin with pictures (any pictures).
