I have seen the same wing bending test for the A380 at the Airbus factory in Chester. It is jaw-dropping. The engineers have to climb into the wing to fit rivets and electrical wires. Sometimes it takes 20 minutes to crawl to the spot they want. Since they take a portable lamp with them, a popular prank was to switch someone's light off when they were well inside the wing. Another anecdote from the Airbus engineer was Boeing had to cut a 747 wing apart because their engineer got stuck in there working on a wing. Can't verify this claim though.
