New reports have suggested that the captain of the Germanwings plane had yelled at the co-pilot Andreas Lubitz to open the door of the cockpit as he tried to use a crowbar to force his way into the cockpit during the horrific descent.
According to the Mirror, Lubitz had put on an oxygen mask and was calmly directing the Airbus A320 into the French Alps as the pilot Patrick Sondenheimer tried to break in.
According to the flight data recording by an investigator, Lubitz did not respond to the captain's continuous calls to open the door of the cockpit.
At around 10:40, the plane hit the mountain with its right wing while passengers' screams and alarms could be heard in the background.
A video clip showing the final moments of the flight revealed that passengers were shouting "My God" in different languages but the footage is extremely blurry.
The clip, shot on a mobile phone inside the plane, shows the passengers screaming and the sound of a metal object hitting the cockpit door.
The footage is being treated as a crucial piece of evidence by investigators.
The Germanwings co-pilot, who is believed to have deliberately crashed the flight into the French Alps, had informed Lufthansa about his earlier bout of depression, the airline has said.
The firm had said last week the Andreas Lubitz had taken a break from flight school training, but refused to say why, reported the BBC.
It has now shared emails from 2009 which showed that Lubitz had told his instructors that he had suffered from "severe depression."
Meanwhile, French authorities said that the remains of all the victims had been removed from the ravine where the plane crashed. They added that mountain troops would return to the site on Wednesday to search for personal belongings.
The search for the second flight recorder will also continue.
