If you go into Boeing's website and go into the gallery and go into the military menu, you notice a plane registered as the BC-17X. If you click on one of the photos, you get what looks to me like a C-17 in Boeing's colors. A few years ago, before the Boeing takeover, this same plane and that same picture were called the MD-17. Is this thing A) real? B) any different from the C-17???
