Seems clear that MH370 was the test run for total electronic takeover of a 777 jet

Simple theory that actually makes sense.
There is evidence that MH370 was electronically hijacked.
All systems, including the most important one, communication, were effectively disabled to prevent pilot communication to the ground. MH370 was simply the test run to ensure smooth operation of the code. The stage was set for the tragedy witnessed today with MH17. Code initialized...cut communications...cut data feed to black box...nose dive into ground....viola. Strategy, planning, testing-the hallmarks of any well conceived operation. Now we shall all see the fallout from this action.
