milky baby-blue skies in the day and no stars at night is natural?
The military has thought long and hard about not just mitigating the heat-producing
“contrails” their C4 agendas require but about making aircraft invisible to sight and radar. (See
General Electric’s 1964 patent US3127608 A “Object camouflage method and apparatus.”) In
the 1980s, stealth programs concentrated on electromagnetics for building radar-evading
bombers. For example, the McDonnell Douglas F-4 Phantom fighter bombers were designed so
that pilots could activate cryogenic superconducting magnets to create an EM “bubble” around
the aircraft. Light striking the EM field would divide and pass around the aircraft and reunite on
the other side—thus, invisibility. But the pilot’s inability to see beyond the invisibility field (“a
4
cloud of ionization” ) forced the military to keep looking for more perfect visual camouflage and
radar-masking. Is it possible to cloak without layer masking? Apparently so. At certain
frequencies, light waves scattered by resonant and non-resonant mechanisms go into opposite
phases and cancel each other out, thus producing invisibility. 5
Nanoparticles are the name of the invisibility game, whether it’s transparent optical displays
on cockpit windows or “obscurants” hiding warfighters from plain sight. Both applications have
to do with engineering the size, shape, and composition of nanoparticles in accordance with the
attenuation properties of light.

Recent design upgrades can now hide a warfighter from infrared and other sophisticated types of viewing, thanks to a
6
range of metallic nanoparticles [with optical properties arising from localized surface plasmon resonance (LSPR) ]
including gold and silver that enhance the attenuation of light in a given region of the electromagnetic spectrum. . .
[P]articles are used to absorb or scatter light in order to block a warfighter’s visibility over several bands of light. 7

The latest is the dielectric metasurface cloak, a super-thin (3 mm) Teflon substrate with tiny
9
8
embedded ceramic cylinders that manipulate EM waves. This ultra-thin metamaterial can work
at 1/10 of missile guidance and marine radar wavelengths, and can be used for EM waves as
small as those of visible light (400–700nm). Radio waves can’t detect an aircraft if radio waves
don’t bounce back to a receiver, and seeing needs light to bounce off the object. Thus, if you can
manipulate the waves, you can obtain invisibility. However, a 6° angle of sunlight can
compromise the cloak, and the cloak can’t cover for visual and radar at the same time (due to the
narrow range of wavelengths).
So you may see a chemical trail laying itself, the jet or drone disappearing before your eyes,
even if you’re looking through IR night vision goggles. The effort to make contrails invisible “to
a size below a humanly visible range” has been going on for decades, the problem being the
chemicals needed to depress the freezing point of water. Toxic additives mixed with the chemical
trails to make them dissipate quickly so they are invisible are even worse for those who must
breathe them in. Even Rolls-Royce’s ultrasonic wave method depends upon chemicals
(“hydroscopic materials”) like chlorosulfonic acid and sulfur trioxide:
