with all the technology having been put on this aircraft...radio vhf/hf, locator beacons, satcom, gps, transponder...even satellite in space dont give much info... all of these designed to locate an aircraft in flight ...not a single one of these technology is able to help pinpoint the exact location of the final resting place of this aircraft on the ground
this tragic event has only proven one thing....aircraft technology haven't really improved much in terms of locating a lost aircraft
