What is Military Cloaking?
"A cloaking device is an advanced stealth technology that causes an object, such as a spaceship or individual, to be partially or wholly invisible to parts of the electromagnetic (EM) spectrum... Active camouflage (or adaptive camouflage) is a group of camouflage technologies which would allow an object (usually military in nature) to blend into its surroundings by use of panels or coatings capable of changing color or luminosity."

"wonder why they choose to cloak...as if we cant notice the nasty white trails they leave."
Why cloak? Maybe to keep from being identified while perfecting their technology for future events, i.e. fake ufo/alien/et invasion to create panic & help usher in the new world order.
5 Trust in the LORD with all thine heart; and lean not unto thine own understanding.
6 In all thy ways acknowledge him, and he shall direct thy paths.
