Two hundred thirty-nine people and one giant plane vanished more than a week ago after taking off from Malaysia.  "Fox Report Weekend" with Harris Faulkner is working to bring you the big developments on this growing mystery. The Malaysian prime minister told the world that this was a “deliberate act by someone on the plane.” How do investigators know that? Tonight, find out about the very important new clue they’ve uncovered.

Also, do you like your Internet web address? The Obama administration says you can keep it, they just don’t want to run the program anymore!  And, our guest Brad Blakeman, former deputy assistant to President George W. Bush, says he knew this was coming and that it could seriously hurt our national security. Harris will ask him: Why is the White House doing this?

Don't miss "Fox Report Weekend" tonight at 7p ET.
