JSE Review by H. E. Puthoff, Ph.D., Institute for Advanced Studies
at Austin, Austin, TX  78759

        To the degree that the engineering characteristics of UFOs
can be estimated by empirical observation, in my opinion the above-
referenced, recently-published book by Paul Hill provides the most
reliable, concise summary of engineering-type data available. [1]
The data were compiled over decades of research by a Chief
Scientist-Manager at NASA's Langley Research Center [2] who acted
as an informal clearinghouse for UFO-related data.  The strength
of the compilation lies in its thoughtful separation of wheat from
chaff, and the analysis of the former into coherent patterns,
including detailed calculations.  Perhaps surprising to the
casually interested, under careful examination the observations,
rather than defying the laws of physics as naive interpretation
might suggest, instead appear to be solidly commensurate with
them, as the following discussion shows.

        One of the most consistently-observed characteristics of
UFO flight is a ubiquitous pattern in which they tilt to perform
all maneuvers. Specifically, they sit level to hover, tilt forward
to move forward, tilt backward to stop, bank to turn, and descend
by "falling-leaf" or "silver-dollar-wobble" motions.  Detailed
analysis by Hill shows that such motion is inconsistent with
aerodynamic requirements, but totally consistent with some form of
repulsive force-field propulsion.  Not satisfied with paper
analyses alone, Hill arranged to have various forms of jet-
supported and rotor-supported circular flying platforms built and
tested.  Hill himself acted as test pilot in early, originally-
classified, versions, and found the above motions the most
economical for control purposes.  Pictures of these platforms are
included in the text.

        In an effort to examine the force-field propulsion
hypothesis yet further, Hill analyzed a number of cases involving
near-field interactions with an apparent craft in which some form
of force was in evidence.  These include examples in which a person
or vehicle was affected, tree branches were parted or broken, roof
tiles were dislodged, objects were deflected, and ground or water
were disturbed.  Under close analysis the subtleties of these
interactions combine to point unequivocally to a repulsive force
field surrounding the craft, while discriminating against propulsion
mechanisms involving jet action, pure electric or magnetic effects,
or the emission of energetic particles or radiation (although the
latter may accompany the propulsive mechanism as a secondary effect).
Further detailed investigation indicates that the particular form of
force field propulsion that satisfies observational constraints is
what Hill labels a directed acceleration field; that is, a field that
is, in general, gravitational-like in nature, and, in particular,
gravity-canceling. [3]  Such a field acts on all masses in its sphere
of influence as does a gravitational field.  Corollary to this
conclusion is that observed accelerations ~100 g's relative to the
environment could be sustained without on-board high-g forces.

        One of the consequences of the above identification of field
propulsion type by Hill is his conclusion, supported by detailed
calculation, computer simulation and wind-tunnel studies, that
supersonic flight through the atmosphere without sonic booms is
easily engineered.  Manipulation of the acceleration-type force
field would, even at supersonic speeds, result in a constant-pressure,
compression-free zone without shockwave in which the vehicle is
surrounded by a subsonic flow-pattern of streamlines, and subsonic
velocity ratios.  An additional benefit of such field control is that
drops of moisture, rain, dust, insects, or other low-velocity objects
would follow streamline paths around the craft rather than impact it.

        Another puzzle resolved by Hill's analysis is that craft
observed to travel continuously at Mach 4 or 5 do not appear to
generate temperatures sufficiently high to be destructive to known
materials.  In other words, UFOs appear to prevent high aerodynamic
heating rates, rather than permitting a heating problem, then
surviving it with heat-resistant materials as is the case of the
Shuttle whose surface temperatures can reach 1300 oC.  The resolution
of this potential problem is shown by Hill to derive from the fact
that the force-field control that results in the prevention of
shockwave drag as discussed above is also effective in preventing
aerodynamic heating.  In effect the airflow approaches, then springs
away from the craft, depositing no energy in the process.

        A further example of the type of correlation that emerges
from Hill's analytical approach is provided by an analysis of the
economy of various flight-path profiles.  It is shown that high-angle,
high-acceleration departures on ballistic-arc trajectories with high-
speed coast segments are more efficient than, for example,
intermediate-level, horizontal-path trips, both in terms of required
impulse-per-unit-mass and time-of-flight parameters.  This he
correlates with the observation that UFO departures are of the
dramatically high-angle, high-acceleration type.

        Also of interest is Hill's analysis of the spectra and
intensity of an apparent plasma sheath surrounding such craft, the
details of which correlate with what one would expect in terms of it
being a secondary effect associated with the propulsion system, for
example, a blue shift and intensity increase during a "power-up"
phase, and the opposite during hover or landing maneuvers.  An
additional fine point that emerges from this analysis is resolution of
the paradox that observation on a direct line-of-sight to a near part
of the craft can reveal a metallic-like structure while the attempt to
observe the outline of the craft, necessarily by an oblique line-of-
sight, results in an indistinct blur.  Analysis shows this to be a
reasonable outcome of an expected re-absorption of reflected light by
the surrounding plasma in the longer-length path associated with the
more oblique view.

        Another typical nugget of information is found in Hill's
discussion of the results of the analysis of a possible UFO artifact,
the famous Ubatuba magnesium fragments claimed to have originated from
an exploded unidentified craft near Ubatuba, Brazil.  Laboratory
analysis of the samples found the magnesium to be not only of
exceptional purity, and anomalous in its trace composition of other
elements, but 6.7% denser than ordinary pure magnesium, a figure well
beyond the experimental error of the measurement.  Hill's calculation
shows that this observation can be accounted for by assuming that
the sample contained only the pure isotope Mg26, rather than the
naturally-occurring distribution among isotopes Mg24, Mg25 and Mg26.
Since the only isotope separation on a significant scale in
terrestrial manufacture is that of uranium, such a result must be
considered at least anomalous, and possibly as evidence for
extraterrestrial manufacture.

        Additional calculations concerning the parameters of
interstellar travel (including relativistic effects), and the
energetics of such travel, have been performed and are included in
tabular and graphical form.  The wealth of material in these sections,
along with discussion of the broad implications of this material,
reveal the dedication and thoroughness of Hill's approach
to his self-assigned task.

        In the final analysis, one must conclude that Hill has
assembled as good a case as can be made on the basis of presently
available data that the observation of some "unconventional flying
objects" is compatible with the presence of engineered platforms
weighing in at something around 30 tons, which are capable of 100-g
accelerations and 9000-mph speeds in the atmosphere.  Perhaps more
important for the technical reader, however, is Hill's supporting
argumentation, based on solid analysis, that these platforms,
although exhibiting the application of physics and engineering
principles clearly beyond our present-day capabilities, do not
appear to defy these principles in any fundamental way.
