malaysia airlines plane

The U.S. government "knows a lot more" than it's letting on about the Malaysia Airlines Flight 17 crash and is "likely hiding [the] truth," according to former Rep. Ron Paul (R-Texas).
All we know for sure is that a plane went down with no warning or communication from the crew. That the crash did not happen during takeoff or landing -- the phases of flight when most accident occur -- somewhat limits the possibilities, but numerous possibilities remain.
