Hundreds of airplane crashes have happened since the invention of airplanes. A multitude of reasons are responsible for these disasters; terrorist attacks, suicides, engine failure, technological failures, and extreme weather conditions.

This week, Germanwings flight 9525 came to an end shortly after it departed from Barcelona, Spain, en route to Dusseldorf, Germany, when the Airbus A320 plummeted into a remote region of French Alps, killing all 150 passengers and crew on board.

This catastrophe came as a shock to Lufthansa Airlines, the owning company of Germanwings, and to the Airbus manufacturing company.

There was no explanation for the crash until the black box from the Airbus was recovered earlier this week. In the recording, the pilot is heard yelling into the cockpit, insisting he be let in to regain control of the plane.

Now here come the accusations.

The co-pilot had locked himself in the cockpit when the pilot left for was seems to be a bathroom break. In the recording, the co-pilot can be heard breathing in a normal manner, dismissing the theory of a medical emergency preventing him from opening the door to let the pilot back in.

Not only was the pilot locked out of the cockpit, but when he initially left, the autopilot elevation setting was changed from 38,000 feet to 100 feet, the absolute lowest setting.

So far, all we know is that the co-pilot intentionally locked the door to the cockpit, all people on board were killed, and the plane is completely demolished.

The black box recording raises a few questions to chew on:

Was the co-pilot suicidal?

A terrorist?

Or did he suffer a medical emergency which inhibited him from opening the door to the cockpit to allow the pilot back in?
