SUBJECT:	Summary of observation of Aerial Phenomenon in the New Mexico Area, December 1948-May 1950
TO:	Brigadier General Joseph F. Carroll Director of Special Investigations Headquarters USAF Wahington 25, DC

1. In a liaison meeting with other military and government intel-
ligence and investigative agencies in December 1948, it was determined
that the frequency of unexplained aerial phenomena in the New Mexico area
was such that an organized plan of reporting these observation should be
undertaken. The organization and physical localisation of units of this Dis-
trict were most suitable for collecting these data, therefore, since
December 1948, this District has assumed the responsibility for collect-
ing and reporting basic information with respect to aerial phenomena
occurring in this general area. These reports have been distributed to
the Air Material Command, USAF, in accordance with Air Intelligence
Requirements No. 4, and to other interested military and government
agencies.

2. There is attached, as a part of this summary, a compilation of
aerial phenomena sightings that have occurred mostly in the New Mexico
area and have been reported by this District Office subsequent to
December 1948. This compilation of sightings is not a complete record
of all reported observations, but includes only those in which sufficient
information was available to justify their inclusion. The observers of
these phenomena include scientists, Special Agents of the Office of
Special Investigations (IG) USAF, airline pilots, military pilots, Los
Alamos Security Inspectors, military personnel, and many other persons
of various occupations whose reliability is not questioned. This com-
pilation sets forth the most important characteristics with respect to
each observation and evaluates each sighting into one of the three classifi-
cations, (1) green fireball phenomenon, (2) disc or variation, and (3) probably meteoric.

3. There is also attached an analysis of the green fireball
occurences in this area by Dr. Lincolm LaPaz. Dr. LaPaz is the
