This page is the starting point for our compendium of historical reports submitted by witnesses in the U.S.A. At present, the vast majority of reports referenced are from the excellent database on Mufon. Non-Mufon sources are indicated. I will also endeavour to include milestone dates in aviation, space and world history so that reports can be viewed in the context of the particular period in history. The timeline originally started at 1940 and ended at 1969 as it would seem that this period of history was when many "contacts" were made and the people contacted now want to "come out" and tell their stories. The timeline then extended into the 1970s as further interesting reports came to light. However, the story does not end there. The first category of reports for 1940 - 1969 comprises accounts that indicated a military or law enforcement connection. These could be reports filed by military or law enforcement personnel, or reports in which such personnel or facilities were mentioned in any way in the text. It also includes a few cases that are of "high strangeness," but may not have the military/LE connection. Included too are cases that refer to some type of blue lights seen by the witnesses. The second category of reports for 1940 - 1969 comprises reports that indicated entities - suggested, seen or encountered up close. This category also contains reports of cases that mention time loss. Quite a number of reports fall into both categories. Starting with 1970 all reports are being listed together, but I am marking them "C" (contact/entity,) "M" (military,) "BL" (blue lights,) "LE" (law enforcement) and "HS" (high strangeness.) In the 1980s the sightings in the Hudson River Valley began to make headlines. Reports from the area are marked "HV" and reports that include triangular craft will be marked "T." NOTE: Some minor edits have been made to facilitate easier reading of the reports. I have not altered the submitters' original wording, spelling or grammar. The underlined headings to each report used to be links to the accounts in the MUFON database.
