Possible speculative explanation for CI UFO incident.

There have been many theories put forward to explain this incident,
from unusual clouds to giant blimps.

In fact the explanation is far more esoteric.
It seems that for the last 20 years the U.S. Military has been
experimenting with a radically new type of
aircraft, based around technologies that most people not "in the know"
are familiar with.

The airframe is based on a carbon nanocomposite combined with spun
metal fibres; a single piece of this material
is almost as strong as bulk diamond but a fraction as heavy.
This is built into a rigid frame which is capable of supporting a
massive structure over a mile long, and several hundred
feet across.

The drive technology is a form of nuclear propulsion that has
similarities to the isomer "energy amplifier" technology in
various issues of "Popular Mechanics" with one main exception. The
hafnium atoms are distributed through a bulk superconducting

material (possibly BSCCO?) which stabilises them in a precise 3-D
matrix that is then energised with the X-ray photon wavelength

needed to induce gamma emission.
The precise spacing is needed due to the standing waves required for
induced gamma emission, and a superconductor also ensures that

radiation-induced defects are rapidly shunted away from the active
area(s).

The X-rays are produced using a ring cyclotron taking up a large area
inside the structure, allowing for the precise control needed

as well as multiple tap-off points for the drive pods.

The working fluid is plain water, obtained using a number of
techniques. Water is vaporised by the gamma emission and provides

lifting force by Newtonian reaction.

Additional power is provided by taps on the main cyclotron to a
thorium amplifier chamber, for emergency bursts of power on takeoff.
This avoids the problems associated with a fully nuclear drive, as
most of the radiation is removed if power is completely lost.

Supercapacitor arrays connected to conventional ducted fans provide a
degree of attitude control as well as stabilisation from

extreme weather conditions.
