Unidentified flying objects are a topic of great concern to people who have too much time on their hands. A retired sheriff from Colorado who has spent the past 25 years looking into UFOs is the subject of a report on the variety show "Sekai Shogeki Story" ("The World's Shocking Stories"; TV Tokyo, Wed., 9 p.m.).

A TV crew follows him to Chicago, where he interviews a pilot and a mechanic who say they saw a flying saucer hover soundlessly above O'Hare Airport several years ago. There's even a clear photo of the object. The show also investigates a UFO sighting that was accompanied by other strange phenomena in a Peruvian village.

In addition, the program discusses a bizarre incident that happened in Mexico, where 300 goats were found dead one morning, all the blood drained from their bodies. Experts say no wild animal could have done that.
