We would often times provide security for them in the desert, we would watch them load the wings and we simply could not fathom how it could get off the ground. There was no spare real estate anywhere under the wings!
Cool, yes add that weight to the fuel weight and it's amazing that they could get off the ground. Once while deployed on a carrier they did an "airshow" for the crew, A-6's put up a "Wall of Water" dropping ordnance in a circle, impressive!
