Colares UFO sightings, Colares Island, Brazil

A December 2008 Project Management Plan from Bigelow Aerospace Advanced Space Studies (BAASS), written under the AAWSAP contract, described events on Colares Island in 1977 as a series of close encounters. It said reports were collected from June to December 1977 and that the island's residents called the objects "chupa-chupas". It quoted an unnamed physician, whose name is redacted, on skin lesions among victims, and stated that the Brazilian Air Force took photographs and recorded data on the objects.

The plan was a proposal, not an incident report. It recommended that the DIA contact the Brazilian Air Force by February 1, 2009 to obtain files, including medical records, on the three-month period. It stated that about 200 pages of the files in Portuguese had been posted on the Internet and that BAASS would check their chain of custody before translation. It also said that part of the files may have been moved to the United States, citing Vallee's book Confrontations.

A March 2009 BAASS monthly report carried an executive summary of Brazilian reports. According to that summary, 48 cases involved doctors and 7 involved photographs, with 11 medical records available. A redacted source from the Brazilian Air Force investigation said "we took about 300 photographs of eight different shapes of UFOs" and that a ship about 100 meters long was photographed. An official, name redacted, described a metallic, cylindrical object about 200 meters away in November 1977. The summary listed 11 vehicle engine failures and one radar datum. It gave no mundane explanation.

A March 2010 AAWSAP Defense Intelligence Reference Document on field effects on human tissue cited the Colares events in a footnote. It described a partial summary of Brazilian Air Force documentation of a months-long series of close-range observations that included medical injuries. The document's own analysis notes that it establishes no causal link between reported injuries and any source.
