Was Germanwings Flight 9525 Taken Out By Terrorism Or A Professional Hit?

Was it a professional hit or terrorism?  

The mystery that investigators are trying to  unravel on what caused the crash of Germanwings Flight 9525 have made a startling discovery in an audio recording, according to a New York Times report: One of the plane's pilots was locked out of the cockpit before the crash.

"You can hear he is trying to smash the door down," a senior military official involved in the investigation told the newspaper, describing audio from the cockpit voice recorder, one of the plane's black boxes.

"We don't know yet the reason why one of the guys went out," the official said, according to the Times' report. "But what is sure is that at the very end of the flight, the other pilot is alone and does not open the door."

What is also interesting is that one of the passengers worked for the U.S. Pentagon. One of the  Identified victims were Yvonne Selke of Nokesville, Va., an employee for 23 years at Booz Allen Hamilton Inc. in D.C., and her daughter, Emily Selke, a recent graduate of Drexel University in Philadelphia. The U.S. government did not identify the third American it said was on the plane.

Yvonne Selke performed work under contract with the National Geospatial-Intelligence Agency, the Pentagon's satellite mapping office, Booz Allen and the Defense Department confirmed in statements after the AP had reported her identity and employment.

Adding to the suspicion of foul play is that the second "black box," the flight data recorder, was found but without any of its contents. The crash apparently dislodged the recorder's memory card which is still missing
