Quote from the document:
“SOURCE: Military
When observer first noticed objects, his first impression was that they were extra large pieces of cardboard or wrapping [paper] tumbling about in an oversize ‘dust devil’. Observer continued to watch them, however, seemed to indicate that the objects [were] held aloft by a force other than aircurrents. They reacted in a manner indicating motive power on their own. All three [objects] acted independently and highly erratically. For example, one object would move up while another would move down and the [third] sideways. Object was observed through monocular (6X23).”
Project Blue Book listed the case as “UNIDENTIFIED.”
