The Malaysian vanished plane may have "pinged" data of itself to satellites above for up to 5 hours after it went off the radar...WSJ reporting a trail of data (transmitted messages) is giving clues about its speed and altitude...and experts beginning to believe 3 communication systems were SHUT DOWN MANUALLY at two separate times! One investigator thinks it's possible it could have landed in a remote jungle area and not crashed in any waters.  Let me know what you think in the comments section below.
