There are numerous flaws with this Condign Report, although there is hardly enough space to mention them all here.

"On an initial reading of the report, I was puzzled why the
author had bothered to perform (or include in his report) such
detailed statistical analysis of such poor data. It occurred to
me that the author was simply unaware of the old computing
adage, "Garbage In, Garbage Out" ("GIGO"). However, my initial
thought was unfair to the author. He actually includes in the
body of the report the following statement: "It is emphasized
however that those conclusions drawn can only be as good as the
reported data" (Volume 1, Chapter 3, page 3, para 2). Given the
numerous complaints in the report about the inadequacies in the
"reported data", I am left puzzled why the author bothered with
such detailed statistical analysis (other than feeling that the
Terms of Reference required him to perform such an exercise,
regardless of his own views).
In any event, that statistical analysis does not in fact appear
provide a basis for most of the conclusions of the report. Upon
a preliminary examination of the Condign Report, it appears to
me that about the only statement made in the executive summary
as a result of the compilation and analysis of the database is
that there is an increased incidence of UFO reports during
periods of peak meteor activity.
Given that the Condign Report's content, in accordance with the
relevant Terms Of Reference ("TOR"), largely relate to the
statistical analysis performed, one might have expected the
plasma-UFO theory advanced in the report to be supported by the
statistical analysis. With this in mind, readers may wish to pay
particular attention to the page of the report which actually
deals with an attempt to find a correlation between UAP reports
and weather conditions (Volume 1, Chapter 3, page 21, para 50).
The relevant page stresses the fact that an attempt was made to
analyze "the most obvious factor - that of the potential of
enhanced electrical conditions in the atmosphere". However, the
results of the consideration of several samples were mixed, with
the overall conclusion being drawn that "there are many
occasions when UAP reports are received when there is no
recorded thunder conditions and hence no enhanced electrical
activity in the form of lightning. On those occasions (other
man-made objects excepted) UAP must be caused by something
else".
It seems almost too minor a matter to note that the results of
the statistical analysis in relation to weather are in fact
misrepresented in the conclusions section a few pages later on.
The conclusions section states "Positive (+0.62) correlation was
shown between thunder (lightning present) and the presence of
UAP reports" [Volume 1, Chapter 3, page 31]. In fact, as noted
above, the relevant page of the analysis dealt with three
samples with mixed results. The first sample (1988 reports) has
a correlation of -0.43 (i.e. a negative correlation, i.e. UAP
are _less_ likely to be reported when there is a high incidence
of lightning), the second sample (1996 reports) has a positive
correlation of 0.62, and the third sample (1988 reports) had a
correlation of 0.19. It is not clear whether the correlation in
relation to the third sample was positive or negative, since the
relevant description of the results refers to a "weakly
positive" correlation but this appears to be a correlation
between days of thunder against days when _no_ UAP reports were
received (i.e. a negative correlation between UAP reports and
lightning). Thus, the conclusion section's reference to a
"positive (+0.62) correlation) merely refers to the one sample
out of the three which most supports the theory being advanced.
The other two samples (and the significant disparity in the
results) are simply ignored in the conclusions section.
Instead of advancing a theory that plasmas caused by weather
conditions are misreported as UFOs (as suggested by some reports
in the media), the thrust of the material relating to
statistical analysis is in fact that meteors are the most
significant cause of plasmas which result in UAP reports.
The reasoning in support of this contention is probably the most
amusing part of the report.
The report does not contain any references to data in support of
the suggestion that plasma bodies are generated by meteors.
Instead, the report refers to the large quantity of matter
entering the earth's atmosphere which "in theory is said to burn
up". The report then simply says that certain issues arise "if
it is postulated that" not all this material burns up or impacts
the surface. (The report acknowledges that there is "a dearth of
information in the scientific press on this possibility").
The report then makes the further imaginative leap that the
postulated further material turns into "meteor plasmas". The
report notes a finding (which may not be considered very
surprising) that "peak reporting periods co-incided with meteor
show peaks", but contends that the reports did not involve (as
one might have expected) sightings of "falling meteors" but were
in fact sightings of "meteor plasmas". The report simply asserts
that these sightings "were clearly events which occurred after
the plasmas had been formed, were usually at low altitude and
exhibited the regularly-seen erratic, bobbing, hovering and
climbing motion which would not [sic] be mistaken by the public
and other credible witnesses" [Volume 1, Chapter 3, paras 53-65
(particularly at paras 54-55 and 65)]."

and you think nobody has heard about all these black and white bits from the 40 n 50's you keep alluding to?
I suspect that many people have not, although I have no way of knowing if you have.
