Investigators have concluded that the plane was deliberately crashed, as the 28 year old co-pilot intentionally made it. The 28 year old pilot had many years experience, and it is unknown yet as to why he committed suicide and what most would call mass murder. Pilots and co-pilots in the past have also done similar actions, some for insurance money, some because they went insane. Only time will tell as officials look into why this young pilot decided on his actions on that fateful day, March 24, 2015.
