park i agree, the wind is different at every level all the way up and it's constantly changing and i've been in little planes, helicopters, and major commercial planes flying at a variety of altitudes, feeling a varried degree of turbulance in all of them, on any given day. i can only base my observations off of what i can see, the planes looked the same shape, and size, which is why i said aprox. i've seen planes have the trail, then no trail, and then trail again...i would think that they probably dipped down in elevation, then went back up where it was colder...maybe that's not what they did and they just flipped a switch or something, maybe it was a weird bust of warmer air pocket they hit, i can't say, cause i'm not up there doing it. i only know what i've observed. i just don't understand it. i want answers that do make sense of what i and many others have witnessed with our own eyes, and i'd like those answers from someone who actually knows. i have looked into it somewhat, not tons because i do have a life, all i can talk about is what i've experinced, and when i don't know something, i ask questions, and try to find the answers,that's all. it's not that i don't think it's possible that it could just be water vapor, but i would be curious to find out if it isn't something else, there are plenty of videos that put doubt in ones mind, again, not that everything on line is true by ANY means, but it makes me wonder at least, and if i wonder about something i'm one to question everything. i don't have all the answers. it probably the illuminati, or the aliens behind it

cause i'm so big on conspiracy ha ha ha ha ha if you guys only knew..lol
and screw..i don't know how i know it's not good other than it's a feeling i have, which i know to you means squat exactly, having a good sense about things doesn't hold water with you i know, and understand quite frankly. i don't get it either, i just know what i feel. that's all i got man lol
and oxygen from plants is not a potentially man made substance realased on purpose into our air. plants happen with or without man being involved in the process. they were here before people were and we effed it all up.
as for my asthma, i have several triggers i have to watch out for..air quality is just one of them, i know how humid it is out by how well i breathe, i don't need a meter or statistics for that one..when it's worse one day than another, i know it, i don't need a weather man to tell me. i feel it with every breathe.
and yes, i understand what makes up a cloud, and we have TONS of them where i live, constantly...all the time blowing right thru...but the lines don't blow away like the clouds are. only prob i have with that. they don't act like clouds. or at least the other clouds around here anyway. i can't explain it.
earth science 8th grade, A+ and a million years ago...
