## EXOTIC TECHNOLOGIES

## INTRODUCTION

1. UAP reports usually describe objects seen at a distance and these reports can only provide, at best, approximate angular speed and size (and often a very vague diameter). For this reason, in the absence of mass or linear velocities the information is almost useless when trying to apply the laws of physics controlling the ability of a 'craft' to land (or hover) and take off again.

The thrust of any object must be slightly less than the body mass on landing and twice its weight for an acceleration on lift-off of 1g. If an object of say 5 or 20 metres diameter were to lift off, using (conventionally understood) thrust then a significant blast and scorching effect must be expected on the surface. No such after-effects are reported in the thousands of UAP reports held in MOD.

2. Exotic Solutions Exotic solutions may be postulated but these often lead to the necessity for some form of force beyond human understanding and contrary to the laws of physics as we understand them. This leads to such ideas as:

- Gravity Cancellation

Teleportation

Propulsion without reaction

Force Fields

3. Intergalactic travel requires four million years for a return trip (travelling at just less than the speed of light), or three years, even to a nearby planet at a velocity of 20Km $ \sec^{-1} $ - a planet on which we can determine no sign of life in the form which would indicate 'beings' and their technology.

## UAPs AS PROPELLED VEHICLES

4. The majority of UAP sightings can be attributed as relatively easily explainable natural or human phenomena - explainable, for

example, as one of the many options explored at the database auxiliary tables. There are, however, the remaining, relatively few events which are not so easily explainable. One of the extreme postulations is that these 'residual' UAPs are, in fact, genuine constructed air vehicles, which use potential scientific and engineering principles which are beyond currently applied knowledge. Thus they must have some sort of propulsion systems which would provide the extraordinary range of velocities and accelerations (and presumably both endo- and exo-atmospheric capabilities) frequently reported. It is only possible to explore the propulsion possibilities which fall within the human realms of conceptual thinking. It must therefore be recognised that there is a limit to real engineering (as within the current limits of understood technologies) and that, if the postulation is true, that methods of propulsion may, in fact, be possible beyond our current understanding in the UK.

5. Several side-issues in which current aeronautical engineering may progress and which may be relevant may also be explored. These include:

- The use of plasmas to reduce airframe drag.

- Plasma 'coatings' as a method of RCS reduction.

- Combined chemical and electric nuclear propulsion.

- Magnetic propulsion.

- Hypersonics.

6. It is surmised that the requirement would be to propel the object at -> Mach 8 or more and that alternatives (as understood within currently accepted engineering capabilities) would be capable of exceeding scramjet or conventional rocket velocities. Research and development on hypersonic technology is expanding, principally in the
