Of course, aluminum wins as it has the lowest density. The passivating oxide film makes aluminum non-corrosive, which is a great comfort to the metallurists and structural engineers responsible for keeping these birds in flight, rather than cracked up over an ocean.

Do I only get one choice? If so, than my pick is aluminum. But you left off the best one: titanium, which is the metal of choice for the aeronautics industry. Ideally: I owuld pick titanium for my fuselage frame; aluminum for the skin; platinum for my reinforcements, and gold for my electronics connections. Gold is by far the best conductive metal, way better than copper, but it is cost prohibitive.

I think the entire airplane should be made out of the same material as the black box!!!!
