1. That's not just wing testing. It's a durabilty test design to put the plane through several ground-air-ground cycles that simulate the stress over the entire frame. It lasts about 3 years

  2. Terrific Music! anyone knows what it is called? Good Demonstration of strength of an aeroplane wing, whenever I flew in a plane, I used to see wings bend and that used to make me scared, that it may snap any minute! But now I know, they can flex quite a bit, as any large and long thing would flex.
