It’s called scheduling. You think that airlines run the same schedules in summer as they do in the fall or the winter? Do you think that the amount of travel goes up a wee little bit starting before November for Thanksgiving and Christmas, but declines at certain times also?

I know aircraft. I know contrails. Something changed in the late 1990's.
Engines with higher overall efficiency produce less CO2 and H2O, but tend to enhance the potential for contrail formation. Improvements in engine efficiency increase the relative humidity of the exhaust plume, because reductions in plume temperature are greater than the corresponding reductions in water concentration as efficiency increases. The estimated growth in contrail coverage due to increased flights and more efficient engines will add significantly to the impact of contrails.

How close to an airport would you need to be to see such patterns as in the above photo?
Snafu your name says it all.
This argument goes on and on, we will not resolve it. I woulf like to ask you a question though.
Something that cannot be argued.
How do you see a contrail at the horizon line?
Could this grid pattern be a search and rescue pattern being practiced by the military or the Coast Guard?

Its easy, a contrail has to be at at the very least about 28,000 ft altitude. What is the visibilty on a clear day?
You cannot see a contrail on the horizon line because it needs to be 28,000 ft up and this would make it over 250 miles away. We do not see that far, it is impossible and makes it so the contrail on the horizon would have to be at half that altitude to be seen with the human eye.

All I can say is you guys are really digging deep to come up with reasons for what I and others have witnessed.
I can't show you a picture because you cannot really tell from a picture. You really have to see it for yourself. And until you do then just pls at least keep an open mind. What have you to gain by debunking this?
I myself doubt the existance of a lot of things but I don't go around saying you're full of it for believing. An open mind is a smart mind. A closed mind breeds ignorance. The World is full of the unbelievable. Ppl used to think the World was flat you know, and the minority that didn't were outcast. But I'm sure you already knew that right?

how can you say without a doubt that these things exist when you state quite clearly above that "you cannot really tell from a picture." so why post pictures at all then?
