Scientific Study of Unidentified Flying Objects (the Condon Report, complete, three volumes)

hoaxes are not part of the subject matter of this chapter, all cases
have been studied under the assumption that all observers involved ~ere
reporting, to the best of their abilities and beliefs, the detailS of
an event which they did not fully understand.
The 3S UFO cases examined in this chapter were classified using
the following criteria:
1. Primarily visual This class includes those cases where
the first and most significant contact was visual, or where the
visual contact was prepondera~lt ar.d more positive than any radar
conta(;ts.
A. Star-like Cuses where the visual reports were of one
or more small, brig~t objects without pronounced motion,
round or without definite shape. (aSb where visual descrip-
tion appeared to be similar to a diffracted star-like object
were also included.
B. ~jeteor .... l ik~. Cases where visual reports resembled meteor
phenomena: rapidly moving star-like object, or small glowing
object, with or without "smoke trails", sparks, fragmentation, .,:;tc.
C. ~lurry light or glow Cases where descriptions were of
a blurry or glowing object of undefined or amorphous shape.
D. Uther Cases not fitting any of the above three criteria.
Six cases were in this SUb-group, including one dark, opaque,
"jelly-fish" shaped object, three balloon-lik~ objects, one
aircraft-like object and one well-defined, structured saucer-
shaped obj ect.
II. Primarily radar This class include~ those cases where the
first and most signifjcant contact was by radar, or where t~e radar
contact was preponderant and more positive than any ~isual contacts.
A. AP-l.ike Cases where the radar scopes ShOWBU a confused
or random distribution of images, blips th.::t showed erratic
or disco~tinuous motion, or other patterns bearing a general
similarity to anomdlous propagatiun CAP) returns.
