A video of the final seconds aboard the Germanwings plane that crashed in France last week has been discovered, reports said on Wednesday, just hours before Lufthansa executives visiting the crash site dodged questions about the mental health of the pilot.

The video was found on a mobile phone belonging to one of the passengers killed on the plane, which investigators say German pilot Andreas Lubitz deliberately flew into a mountain in the French Alps, the Bild newspaper reported.

The scenes seen on the video were chaotic and very wobbly, said Bild, adding screams and shouts of "My God" could be heard, indicating the passengers knew what was happening.
