Yes Brit, what WT said... Even the aircrash investigation episode came to that conclusion as being the most likely... All transponders/communications switched off has meant only one thing in all previous cases; pilot suicide... The under water terrain they're searching is completely uncharted and with huge mountains, cliffs and trenches 6kms deep... Plus, if the plane hit the water in a vertical dive, it's shattered into a million pieces... So its likely not even a full wreck that's there to be found... The search operation has given itself until July to find the plane and are confident it's there in that last bit of search area to be combed... Lets see...I cannot wait I just can't... You should watch the aircrash investigation episode on mh370 it's the most thorough evaluation of all theories and possibilities yet...
