Why is this missile positioned in this odd position? How can it be launched correctly? How this missile is positioned here in this odd position? How this can be launched right from this jet?
You're seeing the Sidewinder on the folded up wingtip of the F-18 that is in the foreground out of frame except for its wing tip and missile sticking up at the bottom.  The airplane is between the camera and the adjacent F-18 who's canopy is visible.  The long lens being used foreshortens and compresses everything distance wise so it looks like the missile is 6 inches from the canopy when it's actually probably 20-30 ft closer to the camera.
