Father of Germanwings pilot insists investigators have not looked at all possibilities
Guenter Lubitz has organised a press conference to insist investigators failed to examine all possible angles to the March 24, 2015, crash that killed 150 people.
Prosecutors claim Lubitz locked the Captain out of the cockpit before he drove the Germanwings flight 9525 into the ground.
Ahead of the Berlin press conference the Lubitz family said: "There remain many other unanswered questions and neglected aspects in the elucidation of the causes."
The press conference is being live streamed from Berlin
There were 144 passengers and six staff onboard Airbus A320 from Barcelona to Duesseldorf.
