I love seen all the insides of the wing when the spoilers come out!!! And how you can see through the wing. Take a look at Dan Rabolt's new shot of the spoilers on a B738 at MDW. Look closely at the wires and pumps under the wing. Excellent stuff.
The 747 spoilers, as seen in John Stewart's photo, are just awesome. Gotta love the huge flaps and huge spoilers.
