Here in Western Australia we have no jet chemtrails, as the air traffic over the metropolitan area is takeoff/landing only (no plausible deniability). We have the planeless chemtrails though, as well as many interesting drone aircraft leaving them. Most we see here resemble a triangular shape. Digital cameras with CCD/CMOS chips make infra-red light visible (invisible to naked eye), just try pointing a TV remote control into the lens of a camera - you should see a white/purplish beam of light. This is the only explanation we have as to why they appear only on digital camera shots. These aircraft can move at enormous speeds, defying laws of momentum. If you google "chemtrail orb" or "chemtrail ufo" you will see many instances of these hidden aircraft working alongside 'jet' chemtrail sprayers, unyet here they seem to work alone... they are always present when the clouds in the sky start appearing in an unnatural fashion. From what I have seen they are part of a global atmospheric manipulation operation.

Question & Answer: What makes those strange figure of 8 trails ... ?

More strange angled planeless trails with strange aerial objects showing up after photography.
Here is a video we shot of a flyover by one low triangular aircraft preceded by flyover of one much higher up - in the opposite direction.

truly laughable that it is automatically assumed off-world technology must be responsible for aircraft which can defy gravity or seem exotic... consider the Hutchinson effect - a backyard shed inventor can levitate massive cannonballs using electric fields powered from a wall socket...
what could a multi billion dollar military industrial complex do back in the 1930s?Why is Laurence Rockefeller behind much of what we now know as modern ET-orientated UFOlogy?
Why has popular controlled culture brainwashed people into thinking UFO (unidentified flying object) automatically equals little green men?
