aircraft and balloons are ruled out."
One document in the Blue Book files shows disagreement with reported
analysis in the 1956 film documentary, "U.F.O.", which was: "Not
aircraft. No balloons. Not birds."
But the following document pretty well sums it up:
"It is the majority opinion of the group conducting this analysis that
these images are light sources. This will explain the non-blinking and
variations in luminosity - but not the velocity or acceleration
factors. In either case, light source or reflective surface, it appears
as if the objects are of a nature which we are not able to identify in
terms of natural phenomena or commonly; known man-made objects.
"There is no indication of what kind of objects could have caused the
images except that they must be of a construction, design, and material
not commonly'' known. This is indicated by the computed acceleration
rate and elocity (answer S). For the same reasons, birds, aircraft and
balloons are ruled out."
