The Guardian reported that two senior military observers said they watched a mysterious black triangular object flying at an extraordinarily high speed over a sensitive site in the western United States earlier this year. The account was written by Richard Luscombe and published on Friday.
According to The Guardian, the observers are anonymous, and the account was included in the latest tranche of reported UFO sightings released on Friday by the Trump administration. The Guardian's headline calls the material new Pentagon UFO files.
The Guardian also reported that the unidentified object "vanished suddenly and silently." The Guardian's headline refers to black triangles in the plural, while its summary describes a single black triangular object, and the summary does not explain the difference.
The summary of the report available for this story ends mid-sentence, so any details that appear later in The Guardian's full article are not included here. The summary does not identify the western site, explain how the object's speed was measured, or describe how the observers' accounts were checked. The claims come from anonymous observers, and this story does not independently confirm them.
This story relies on a single report from The Guardian, and no other source was reviewed for it.
