Before about 2000 I never saw the "chemtrails" that I saw in person and I have never seen them in movies, TV or pics from time periods before this.

The second German sighting occurred on May 9, 1919, when a pilot flying over Berlin at about 26,000 feet noticed the generation of a cloud stream that extended for about forty miles behind his plane. This stream eventually spread out to form a cloud layer that was about 3,000 feet thick. The pilot saw a similar phenomenon two days later.
The spreading out of jet contrails into extensive cirrus sheets is a familiar sight. Often, when persistent conditions exist from 25,000 to 40,000ft, several long contrails increase in number and gradually merge into an almost solid interlaced sheet.

please explain - how - by only looking at pictures - you can distinguish contrails from alledged chemtrails
and further - is your " analysis " going to take hi-bypass turbo fan useage , and the rise in flight numbers into consideration ?

Simple contrails cant make x cross the skies as contrails only last for a few seconds then vanish these so called chemtrails last for a lot longer.

Year round at the attitudes jet fly the temperature is pretty constant. Or within a pretty narrow range. What makes me wonder is why on some days there are trails while on other days there are none. You would think the trails would be more consistent from day-to-day if it were just water vapor in jet fuel. Unless the water content of the fuel is changing all the time ii seems a little suspicious to me.

The temperature stays relatively constant as you say, it's the relative humidity that varies a lot

I didn't mean contrails weren't there. I meant chemtrails like the ones we have seen weren't there.
