This picture is controversial, and has been called into question before. Previous analysis showed that the CCD grid, which manefests as an 8x8 grid patten in digital camera shots and scanned photographs, was consistent across the photograph. This would make editing the photo very difficult, especially with the power line running across the picture.

I've created an image where this 8x8 grid can be seen and marked some of the corners with black dots, to aid in viewing the grid:

But, hey, look! I found the missing part of the trail!!!

Will also mention that contrails can leave broken trails, as I have seen this with my own eyes for verified normal flights with Flight Explorer. However, there are differentiating factors between contrail strips and a Chemtrail strip based on my observations.

Contrail strip
--------------------
a. Appears on FE as a normal flight
b. Area of abscence of trail may appear several minutes after the trail is created, as a portion of the contrail sublimates.
c. Area of (non-abscence of) trail has a relatively short persistence.

As a full-fledged debunker who does a lot of digital photography and uses Photoshop 6.0 every day, I would really like to tell you that the photo at the beginning of this thread is an obvious fake.

Unfortunately (for me, anyway), I can't. Although I don't have access to the original .JPG or .RAW file, your comments on the consistency of the CCD pattern (and I can see that) mean that either the photo wasn't re-touched at all, or the 'faker' knows a lot more about his clone tool and Wacom tablet than I do about mine. I think the photo is un-edited.

But, despite what one of your visitors said, I do not take the gap to mean that the aircraft 'shut off' then 'started' some spray device.

Your correspondent mentioned that the "abruptness" of the contrail was suspect. Since I'm not an atmospheric scientist, I certainly wouldn't be able to comment on that; perhaps the threshhold of temp/RH is enough to cause an abrupt cessation, perhaps not.

However, if you've ever watched ag planes turn their sprays on and off, you can see an incomplete (i.e., not "abrupt") line of spray prior to the start or resumption of spray trail -- probably as the nozzles re-fill. I'd assume the same thing would happen in a high-altitude regime, but then again -- I'm no atmospheric scientist.

The bottom line, though, is that I agree with you; from what I can see, the photograph has not been edited.

Regards,

In wanting to more completely understand your "incomplete line" seen in Ag spraying, I will present a couple of photos. Do either of these photos resemble the phenomenon you speak of?

"Let's assume that we're seeing a contrail, not a chemtrail. Could that visual result be achieved if the engine cut out for a brief period and then cut back in again?"

Possibly, but I couldn't say for sure one way or another. That very seldom happens anyway. Anyway, if they did have an engine failure, you would probably see a continuation of some sort of exudate-cloud --- produced by the pilot, not the aircraft!

Mr. Thermit, you said:

"Do either of these photos resemble the phenomenon you speak of?"

The ag-aircraft spray-trails I have seen while driving through agricultural areas typically had a thin "proto-trail" for about a half-second, at the middle of the nozzle assembly, then rapidly spread outwards to the entire width (20 ft?) of the nozzles. My guess (and this is only a guess) was that, as the tank was opened and began to pressurize the nozzle assembly, some of it escaped through the nozzles closest to the center of the assembly.

At the time I assumed that it was because the main conduit from the pesticide-tank to the nozzle assemble ran down the center tube, thus pressurizing the center nozzles first.

However, I've never been within five feet of an ag-cat with its nozzle assembly attached, so this is merely speculation on my part.

But my point is that (it seems to me) there might not be "abruptness" at the termination point of any contrail or spray-trail. This means that a sudden cessation might not be a discriminant of "con" versus "chem".

Or it might. I'm simply not qualified to make any conclusion. I guess I'm a lot dumber at 56 than I was at 26.
