And what major change occurred around 2000 that would cause more persistent contrails to form?
By the mid-1990s all old jets had been upgraded to the new engine configuration and all new planes coming off the assembly line were equipped with the most modern versions. But this new next generation of jet engines had one curious "side effect." They produced contrails that can persist for more than 24 to 36 hours! Condensation trails from first generation jet engines generally only lasted for about 10 or 20 minutes and then they disappeared. But these new "chemtrails" persist all day long – and with 35,000 commercial flights in the US air lanes each day, these new persistent contrails produce numerous crisscrossing, tic-tac-toe patterns all over the sky. So, why do the new contrails now last all day long?
The black oily spot from the first generation engines quickly absorbed the heat from the sun and caused the ice crystal balls to melt within several minutes. When the ice crystals melt, they disappear.
The new ultra-clean exhaust of the next generation jet has no black oil spots in the center of the contrail ice crystal balls. The heat and light from the sun pass right through the clear ice crystals of these next generation contrails as if they were transparent. They do not absorb any solar heat and thus do not melt. They may remain frozen and persist, looking like long thin high cirrus clouds for 24 to 36 hours before they simply disperse but do not melt and disappear.
"Chemtrails" theory then, is that "normal" jet aircraft contrails disappear in a few minutes, whereas "chemtrails" persist for hours, and therefore are not "normal" and must contain some covert element to make them persist. This, however, is based on ignorance of aviation technological advancement and a working knowledge of atmospheric physics – neither of which were the general public kept abreast of by the mainstream media or public education. Persistent jet contrails can be entirely explained by science without having to resort to a "conspiracy theory" scenario. They appear to be no more than the natural result of the introduction of the hi-bypass turbo fan, improved jet fuel
Yes, but it doesn't answer the fact, that if there's so much fuss about contrails/chemtrails, why there wasn't a simple public statement, explaining the fact of increased contrailing in the skies due to upgraded engines.

I was NOT born out of an egg, as we say here in Holland,
The difference is that contrails dissipate, whereas chemtrails are formed using grid patterns and they spread out to form clouds that remain for hours blocking the sun and making the sky look dirty.

So you have studies meteorology and know that contrails cant dissipate due to weather conditions at flight altitude?
How many times is line going to be repeated, it was one of first lies or misunderstandings told about chemtrails.
Yes contrail sure can linger and spread eventually covering large portions of the sky from ones perspective.

Contrails have been doing that as long as planes have flown. They reported the first contrail spreading into a cloud in 1918.
Does questioning someone's education suffice as debate?
Does saying one has misunderstood prove a point?
Sure, contrails can linger. I"m not speaking of contrails.
I am speaking of chemtrails that are a direct result of Geoengineering.
