UFOS Northwest does not necessarily believe that every report received is accurate and true.  We try to filter out hoaxes and obvious fabrications.  (Some cases where hoaxes are a possible explanation are still displayed.) We strive to present reports as received and perform an analysis if time permits.  In many cases data are incomplete and credibility of witnesses is unknown. Due to time constraints and the high volume of reports, some of these reports have not been investigated.
