I recently had to sit through a presentation by an X-er in which was played a very smug GoogleX video that spliced an annoying amount of apollo- and shuttle-era space exploration footage to pump up what was essentially floating cell towers (Loon). I found it quite disrespectful to the apollo engineers, and grasping of Google PR, to try and equate what they're doing to landing on the moon. It went quite beyond the bounds of what is reasonable with a straight face, for my tastes.
