SHANGHAI (Reuters) - Shanghai appeared convinced on Friday that an unidentified flying object had visited China's commercial capital.

Usually staid official newspapers insisted Thursday's sighting was no vision.

"UFO darts across the city's skyline,'' screamed a headline in the official Shanghai Daily.

"UFO appears in the sky over Shanghai,'' the Wenhui Daily said in a front page story with color photographs.

Nearly 100 people claimed to have seen a cylindrical object with a flaming orange tail moving over the western part of the city for about an hour on Thursday afternoon, the newspapers said. They offered no theories on what it might have been.
