There are three paragraphs in the article discussing that photo and the surrounding controversy. It would have been annoying to make the reader have to leave the article to actually see the photo.
That photo was unremarkable when the album was released, and was in shop windows everywhere. It's hardly erotic -- c'mon, it's an 11 year old!
[edit: I re-read the part of the article, and I don't remember record shops freaking out, which I surely would have heard about at the time. Even the company that sent out albums unasked-for to household sent it out]
There are still pioneering achievements in modern aviation. The 787, for its carbon fiber fuselage and advanced computing system, and the A380, for its sheer size, come to mind. If a measure of the import of new technology in aviation is whether it's replicated across future designs, then the 787 definitely qualifies. Both its carbon fiber technology and computing technology are in the process of being adapted to new (future) applications as we speak.
