Locating the plane... (Score 1)

Most of the speculation could be ended if the plane or flight recorders were found. I'm surprised that this day and age this should be so difficult. The methods I would apply are: 1) radio triangulation of airplane signals - weather conditions may not have been favourable, but if the automated messages were received by Airbus, surely they must have been registered with various military electronic listening posts to pin-point the last known position of the plane prior to impact. 2) impact detection using Hydroacoustic listening stations - according to articles these kind of devices can detect the explosion of 300kg TNT half way around the globe, so my thinking is that a high speed impact on a large plane on the surface of the Atlantic should not go unoticed. Also there seem to be >3 CTBTO stations available in the atlantic (http://www.ctbto.org/map) for this.
