This is what thet call the Marrying dock, it's a massive jig that comes together from both sides of the plane and fixes the wings in the exact place

Airbus 380 Factory in Toulouse France 2007

I was very happy when my son-in-law told me he had tickets for a very first and specially day out to see the Airbus380 Factory in Toulouse France were he worked on the wings being married to the planes, it was apsolutly breath taking,i could not believe the size,and there were over eight planes being constructed at one time,the Factory was enormous,and that part on the photo's was just one part of a massive Factory area.
A memorable trip and a fantastic day out.
