I was on a photo assignment in San Pedro Sula, Honduras. I went up on the second story of a small building to take some panorama shots of the mountains in the background and the area in general.
While doing my pre-edit of the photos that evening is when I first noticed the object on the screen on my camera (Canon 40D). Note the object was moving so fast my naked eye never noticed it until that evening while I was doing my pre-edit.
