There's some debate over at Flickr concerning whether this image is real or photoshopped. The person who took it (Kris Kros) swears that it's real. But doubts have been raised by Hugo who argues that "such a crisp capture of a jet, in front of an extremely detailed moon, in complete darkness, with no apparent noise, was quite extraordinary." I can't tell one way or the other. Though Hugo is absolutely right to point out that in almost all pictures of planes flying in front of the moon, the turbulence of the jets is visible... but it's not visible in this picture.
