SBD-5 Dauntless -parked at Cable Air Show..

 Perforated dive and landing flaps.  When landing, the flaps are lowered separately.

 Twin .30 caliber machine guns in the gunner/radio operator's compartment.

Unfortunately, I didn't get to see this magnificent aircraft fly at the air show. It seemed that the aircraft that I found to be most interesting were on static display.  Eagle-eyed readers may notice that the center-line bomb-crutch has been removed from this aircraft.
