Reply #170: This is denial, not argument.

As I've said elsewhere: you are ruling out, a priori, an argument, not responding to it rationally, much less refuting it. Photos prior to 1998 - except for cloud-seeding photos - do not show these trails: dense, refracting, manytimes oily-looking, manytimes precipitating particulate matter or strings of "cobweb" material, coming out of planes in a puff-puff "donuts on a rope" pattern suggestive of particulate coming out of a cycling PUMP. Remember the story of the Emperor's New Clothes, people. That story is about the ubiquity of subconscious FEAR controlling our perception (what is it today? Orange alert? are we ever given a reason or suggested to respond rationally? NO, only to raise our level of FEAR). All you have to do is look at this trails spreading out to create cloud-cover: contrails (of ice, water vapor) do not, cannot, unpack to cover the whole sky over a period of many hours. No amount of head-in-the-sand "debunkers" can change the fact of what is happening. Check out carnicom.com.
