BS, Mark, if you have a valid point then make it honestly. The photo on the Cessna is a lady in a modest one piece swim suit, in no way, porn soft otherwise. Your examples are much more riskque and one is even topless. Not a valid comparison. "semi naked" is not a true desciption of the photo on the Cessna.
I doubt it young girls at EAA would think nothing about the photo, and any womens store or dept store or newspaper is going to have adds that are much more up to date.
