Where do all these references obtain their information? It all looks like a lot of B.S. just to stir the conspiracy theorist pot. Having been heavily involved in deploying such comms systems to land & sea based vehicles (the same satellite systems were used (yes, I even know which constellation of sats are involved in the RR engine reporting system)) I can say most of what I read on provided links are obviously idiots fools trying to fan the flames. The at-gate reporting system wasn't deployed on that aircraft and probably never will be. They are limited to ACARS for the engines and that operates in the VHF bands.The up-link is in the 130mHz region and you can hear the sat down-links with any radio capable of tuning in a range around 150mHz. The sat constellation repeating ACARS IS NOT CAPABLE of direction-finding shots. They do have the ability to report which antenna had the strongest signal strength.This is why the engineers provided two arcs on a map to provide the PROBABLE location of the last up-link. The pilots do have the training (and must have it) to minimize 'squawking' by turning such systems off. The intent is to help minimize radio congestion while on the ground or in congested air space. That and ground-based transmissions in the 130mHz range are illegal in many countries because that band is allocated to government and emergency services - Much of the U.K. all of the U.S. is this way. Yes, someone definitely knows where it went but they can't tip their hand, and won't. Anyone ever heard of NROL? I own two of the patches. The second one I bought from a friend  The CS geeks really need to provide some credible sources.  >>Edit... 'Idiots' was a bit strong. I've been the 'idiot' many times. One other tidbit..... Those sat constellations aren't arranged to provide continuous communications. In the higher and lower latitudes there are noticeable time gaps between satellite connections. The reporting equipment not only has a schedule for reports but also waits for a satellite to be within range. Being at 35,000 feet helps a little but not as much as one would think. The sat down-link antennas are pointed downward in a cluster producing coverage spots. The reporting equipment must be in one of the coverage spots, regardless of altitude.
