`II`

   Two British policemen were(19) sent to investigate a flying saucer on March 31, 1989, the day before April Fool’s Day. When the policemen arrived at a field in Survey, they saw a small figure wearing a silver space (20) suit walking out of a spacecraft. Immediately the police ran off in the opposite direction. Reports revealed that the alien was in fact a small person, and the flying saucer was a hot air balloon that had been specially built to look (21) like a UFO by Richard Branson, the 36-year-old chairman of Virgin Records.

    Branson had planned to (22) land the balloon in London’s Hyde Park on April 1. However, a wind change had brought him down in a Survey field. The police received a lot of phone calls from terrified motorists as the balloon drifted over the motorway. One lady was so (23) shocked by the incident that she was crying as she was (24) describing the UFO to a radio station.
