◆ PARALLAX

I know this subject has been done to death here, but I am starting a fresh thread because the usual yelling match is obscuring what might be the only testable part of the whole chemtrail business: persistence, routing, and timing.

For the last six weeks I have been keeping a crude sky log from my back garden and from the roof of the print shop where I work. I am under no illusion that I am doing "science" in the university sense, but I am at least trying to avoid the normal trap of seeing one weird trail and shouting BLACK HELICOPTERS.

What I have:

1. Date/time of visible trails.
2. Approximate direction of travel using a compass.
3. Duration until dissipation or spread.
4. Local humidity, pressure, and temperature from the Met Office regional page.
5. Comparison to known civil air corridors where I can get them.
6. 35mm photos, usually with roofline reference.

What is bothering me is not simply that some contrails last a long time. I understand that at altitude, ice crystals can persist, and I understand that contrails can spread into cirrus. Appleman's 1953 work on contrail formation is not secret. NASA pages say essentially the same thing. Fine.

The oddity is the grid behaviour.

On five separate mornings since January, the visible trails were not aligned with the usual west-east commercial traffic pattern. They appeared in two sets, roughly perpendicular, with repeated passes over the same section of sky. The first set ran NW-SE. The second set ran NE-SW. Within 90 minutes the sky went from clear to a milky sheet. It was not ordinary cirrus arriving from the horizon. It was manufactured locally in the sense that I watched the filaments thicken where the aircraft had been.

Possible ordinary explanations:

A. Military training routes.
B. Holding patterns at high altitude.
C. Wind shear making parallel routes appear crosshatched.
D. My route assumptions are wrong.
E. Coincidence plus observer bias.

Possible less ordinary explanation:

Someone is deliberately increasing reflective haze or testing aerosol dispersion under cover of normal air traffic.

Before the usual debunkers begin, I am not claiming proof of aluminium, barium, polymer fibres, or population sedation. I have no sample and no lab result. But the "only water vapour" dismissal is not adequate either, because water vapour can be deliberately used as a carrier phenomenon or a visual marker. The question is not "can contrails persist?" The question is "why these passes, why this geometry, and why now?"

Relevant scraps:

- 1996 USAF paper "Weather as a Force Multiplier: Owning the Weather in 2025." Yes, I know it is speculative and not official policy. But speculative military doctrine often marks the outer boundary of current imagination.
- Public cloud seeding history goes back decades. Nobody disputes deliberate atmospheric intervention as a category.
- NASA and FAA have studied contrail cirrus climate effects. Again, not secret.
- Several patents exist for aerosol dispersal and atmospheric modification. Patents do not prove deployment, but they do prove the idea-space is populated.

What I want from this thread:

If you see a heavy trail day, post the following:

LOCATION:
DATE:
TIME START:
TIME END:
DIRECTION OF AIRCRAFT:
WIND DIRECTION AT GROUND:
WEATHER DATA SOURCE:
DISSIPATION TIME:
PHOTO? Y/N:

Do not post "my throat hurt after spraying" unless you also include pollen count, humidity, and whether half your office has flu. Do not post about depopulation unless you can separate it from your eschatology.

There may be nothing here except persistent contrails plus frightened apes pattern-matching the heavens. But if there is a program, the pattern will be spatial and temporal before it is chemical. The sky is a ledger. Start keeping accounts.

Good template. It is the first one of these threads that reads like it could survive being copied into a notebook instead of turning into fog and shouting.

This also ties back to the weather-paper thread. If people post county, clock time, wind, ceiling, temperature, trail direction and dissipation time, then we can compare logs. Please, logs not throats.

I would keep two classes of entry. Hard-timed is when you have the watch in hand and write the start and end as they happen. Soft-timed is when you reconstruct from memory later that day.

Do not mix those without marking them. A weak hard-timed record is worth more than a dramatic soft-timed one.

I know you said no throat stuff but I have to say it anyway. Every time the white grid sits over the estate my throat gets raw by evening. It is not normal winter sore throat. It has happened three times now.

My wife noticed it too and she does not even read this board.

Tom, put that in the margin until you can add pollen, humidity, flu in the house, smoking, heating type, and whether you were outside. Otherwise it will sink the useful part of the thread.

LAMINAR, the template is sound. I would add cloud base by plain description if no instrument is available: clear, high veil, broken low, overcast. Even rough weather-notebook language beats a memory argument.

Seconding the praise for the template. Please use UTC or state local offset every time. Bearings too, even approximate, because north-east to south-west means something different once people start comparing across villages.

I would like radio conditions in the notes if any hams are watching. VHF lift, aircraft-band traffic density, and any odd fades. Not proof of anything, just another clock running beside the sky clock.

It is water vapour, goodnight.
