From a scientist: “The primary propulsion system is electro-magnetic flux directional positive force generating system. The secondary propulsion system is a anti-gravity (using fluid plasma) directional negative force generating system. Remember, these are our terms. The entire craft can be a super conductor or a super capacitor depending on how the propulsion system is configured. Like I said, the system is extremely complicated. Unless you understand the entire system, which we don't, you won't understand what I am saying. The electrical system works on a vacuum vacated energy principle. This system generates an unlimited amount of power. The Visitors have determined that hydrogen has many more isotopes than we thought. H5 is one isotopes they harnessed and use as a catalyst inside the power device.”
What is a negative force generating system?
This was something proposed a long time ago by engineer Leonard G. Cramp in trying to explain flying saucer propulsion when he alluded to the bi-field theory, the G field and the R field. He says, “Of the G field-propelled craft discussed earlier (the use of an artificially created gravitational field), we could say that it was gravitationally moved towards its point source, or, due to a decreased gravitational field strength above it, it is repelled by the ‘denser’ space beneath, and either could be equally true…of the R-field (Repulsion Field) vehicle, we might say that was repulsively moved away from its point source or, due to the increased gravitational field strength below it, it is attracted to the less ‘dense’ space above, and either could be true..” Leonard goes on to propose that both G-field and R-field, one convertible into the other are in use in UFOs.
Paul Hill, retired and now deceased NASA scientist in his excellent technical analysis of UFOs in his book Unconventional Flying Objects considers that the UFO generates a repulsive field. He says, “it is shown that the UFO field is not of the static-electric or static-magnetic type. Rather, it appears to be a quasi-static field of a negative-gravity type. This is concluded because the data shows that the UFO field repels all mass, not just electrically charged or magnetic materials.”
He also mentions, like Cramp, before him that the field must have some degree of field focusing, that it goes out predominantly in one direction in order to give control.
These ideas now invoke a new idea in the field of cosmology termed dark energy. Dark energy is thought to be smoothly distributed throughout the universe. Dark energy has a strong negative pressure of the same order as its energy density. Dark energy interacts only through gravity. Dark energy produces a repulsive force and drives the expansion of the universe.
The point to be made here is that the extraterrestrial starship engineers have harnessed both gravitation and repulsion as a means of traveling through interplanetary and interstellar space. Perhaps they have even been able to artificially create a wormhole tunnel to distant parts of the galaxy through using their control of gravitation and dark energy.

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.  The data were compiled over decades of research by a Chief Scientist-Manager at NASA's
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.  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 degrees C. 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
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.
