I was on vacation in italy, traveling by high-speed train from rome to naples. i snapped some photos of the passing landscape out the window during the course of the trip. when i returned home i downloaded the photos to my computer and was showing them to my husband. at one point he said, "what's that up at the top of the screen? it looks like a ufo." i hadn't even seen the object when i was snapping the photos, so it was a surprise once he pointed it out to me. then i noticed that it appeared in a sequence of four photos taken over a period of 12 minutes and at a traveling speed of about 90 mph. that would mean we covered a distance of about 13 miles from the first to the last photos, and the object was still visible in the sky. zooming in on the photos, the object looks clearly like the stereotypical "flying saucer." i only wish i had spotted it at the time so i could have zoomed in and taken some video too. i'm not sure of the geographic location, but we were maybe an hour outside rome heading south towards naples.
