UAP ~ Unidentified Aerial Phenomena
"An unidentified aerial phenomenon (UAP) is the visual stimulus that
provokes a sighting report of an object or light seen in the sky, the
appearance and/or flight dynamics of which do not suggest a logical,
conventional flying object and which remains unidentified after close
scrutiny of all available evidence by persons who are technically capable
of making both a full technical identification as well as a common sense
identification, if one is possible. (Haines, Pp. 13-22, 1980)

The term "Unidentified Aerial Phenomena" or UAP is an attempt to address the fact
that not all UAP are described as unidentified flying objects or UFO. Many are simply
described as unusual lights. NARCAP feels the term "UAP" more accurately reflects
the broad scope of descriptions in aviation reports as well as the possibility that these
phenomena may arise from several different sources.

The answers to the questions regarding the existence, source and nature of the
subcategory of UAP referred to as UFO will be found in the data. Given that pilots do
report aerial phenomena that they describe as structured objects, NARCAP feels it is
appropriate to give attention to the witness' description of what was seen or detected
and engage it objectively.
