"Fact: If two similar aircraft are at the same altitude and flight path one can't leave a contrail without the other leaving one also. Either
they both do or they both don't.
Observation: On several occations I have witnessed one aircraft leaving a contrail that doesn't dissipate while all other aircraft in the area leave
Since the typical altitude of aircraft leaving contrails is around six miles, there’s no possible way you can determine if two aircraft are even
with two or three thousand feet of each other vertically. If you’re like me and your eyes are about three inches apart, the best distance you can use
for depth perception is about 750 feet. Any further, and you need visual cues like trees, houses, mountains, etc to determine which object is closer.
There aren’t any visual cues when you look straight up -- there’s nothing but air! And remember, there can be a threshold differential
(either temperature or humidity) at an altitude delta of only a couple hundred feet.
“Fact: An aircraft can not turn a contrail on and off at will. The water content of the air in which the aircraft is traveling may change, in turn
increasing or decreasing how much contrail is being produced, but it can't just stop and start in short segments.”
See the example in my first post. If the temperature is below minus 40 deg and the air is saturated, the contrails will persist, if either of
those conditions do not obtain, the contrail ice will sublime within a minute or so. It is that simple. And you know that you have those
sudden changes in the atmosphere -- that’s why clouds have edges!
”Fact: If the water content of the air is too low a contrail can not be produced. This condition being very common in states like Arizone and New
mexico but can acure any where in the U.S. being more likely in the western states.”
Not necessarily. It is not a matter of the “water content” alone but of the relative humidity, which is a function of both water
content and temperature. At minus 40 degrees, it only takes about one one-hundredth the amount of water molecules per specified volume of air
to saturate it as it would if the temperature were, say, 90 deg F.
It’s easy to see how important temperature is to saturation. Fill a glass full of room temperature water, then add sugar, a spoonful at a time,
and stir vigorously until it’s dissolved. Sooner or later, you’ll reach a point where, no matter how much you stir, no more sugar will dissolve; in
other words, the water is saturated.
Now put the water in the microwave and zap it for a minute or so. You will notice that the extra sugar will dissolve, and you can add another
couple of tablespoons (as long as the water is hot) and it will dissolve. This experiment shows graphically the importance of temperature on
saturation, whether of sugar in water or of water vapor in air. It also explains such things as “supersaturation”; but that’s not really germane to
”Fact: Ariel spraying of any type, like crop dusting for example, does not get performed in high wind conditions. High wind conditions making it
too difficult to contain spraying to targeted area for the crop dusting example. Observation: I have yet to see any non-dissapating contrails on very
At the levels at which contrails appear, there is a high energy wind pattern called the Jet Stream. Although the air may be still where you
are on the ground, it’s not that way at 35,000 feet altitude; a quick check with Flight Explorer will show you that.
”Fact: Contrails are usually only produced at higher altitudes but may occur at lower altitudes in very rare conditions. Observation: Almost all
non-dissapating contrails that I have witnessed have been at lower altitudes. I have even witnessed an aircraft make a tight U-turn at an altitude no
higher then low cloud cover, leaving a non-dissapating contrail which visibly expanding while falling to ground level in no more then half an
I haven’t, and all the photographs I see of “chemtrails” show contrails at very high altitudes.
”Fact: The Air Force currently has a large inventory of the no longer produced McDonald Dougles DC-10 that have been converted to tanker aircraft.
Observation: I have personally seen these aircraft at Travis Air Force Base in Vacaville, Ca.”
So have I, and my former employer is McDonnell Douglas, not “McDonald Dougles” And I have personally seen these aircraft all over,
including Delta flight 86,, Los Angeles to Tokyo, which I personally flew four times in 2001. Most DC-10s have been converted to cargo carriers, and,
as you said, the Air Force has many tanker versions, called KC-10s, in its inventory.
Are you saying that is some sort of evidence for the existence of a "chemtrail" plot?
“Fact: All aircraft excluding some small single engine aircraft have the ability to dump there fuel loads in preperation and likelihood of a crash
True. Most aircraft can jettison their fuel loads in case of an emergency landing, to improve the plane’s handling characteristics, and to lessen
the chance of fire upon landing.
”Observation: I can't say that I know what a tanker coversion consist of ….”
I can; my company builds more aircraft, including tankers, than any other company on the Planet.
“… but I do know that what ever the tanks are full of, wether it be fuel or what not, can be discharged at any altitude at any time.”
Yes, that is correct. Is that some sort of evidence for a “chemtrail plot”?
”Fact: There are several commercials, shows and even cartoons on T.V. that have scenes were the sky can be seen with contrails in them.”
Why are you surprised by that? Aircraft contrails are more and more common nowadays, as more and more aircraft are in service and more and more of
the old turboprops are replaced with jet commuters.
”Observation: I have seen too many to list but I like this one because you don't have to believe me, you can easily check it out for yourself, and
when you see it's true you have to ask yourself why? Why would anyone want to fill a sky seen with anything other then a natural blue sky, unless
maybe they want us to think that white lines across the sky are completly natural and normal. This way when we go outside and see white lines in the
sky we don't even think twice about it. We won't ask any questions.”
Maybe it’s because skies with contrails in them, in the year 2004, are the norm nowadays, just like you now see roads full of cars rather
than horses and buggies.
You have made a lot of comments and facts and observations; most of your “facts” are true; and many of your observations are valid. But I don’t
see that you’ve shown any evidence that persistent contrails are anything but ... well, persistent contrails!
