That is a good one...I have asked every person i can about seeing lines, not one ever remember them EVER persisting, but all dissipated in under 5 minutes, usually under 2 minutes.
I’m 52 and I remember seeing them all the time when I was a kid in the ’60′s. I remember because I asked my dad, who was an engineer, to explain to me what caused them.
Yeah, I gotcha, many times for hours. Maybe most of the day, I don’t know, I never spent that much time looking at em.
I’m not epic old, but I do remember some contrails lasting for hours, arching over the sky and you could follow it right to the horizon.
The Glynco Naval Air Station was working in full force when I was born in 1947.
I am also in between Savannah and Jacksonville that are both homes to military air stations.
Yes I remember the contrails growing up and enjoyed seeing the jets in the sky.
We had many sightings a day due to being so close to the ocean,
I used to sky watch all the time with my friends when we were little kids… we all remember contrails in the sky and them lasting for a few minutes, perhaps up to an hour, but not the whole day, not EVER.
im not much older than you op im 25 and remember seeing them as a kid in the early 90s. i would watch as a plane approched a contrail and expected them to crash when it hit them.
I’m 51 & live in the South Pacific.
Down here there was only 1 overhead air route when I was a kid – between 2 cities 200 miles north & 200 miles south (and it’s still the same there now). I remember seeing long contrails along that route before I started working – so in the early 70′s and late 60′s – sometimes the one from the flight in 1 direction would still be there when the a/c went back in the opposite direction an hour later.
I remember them spreading out a little – but not over the “whole sky”
I’m in my 40s and grew up in SW PA. I used to love looking into the summer sky and seeing long CONTRAILs. I would follow them across the sky to see if the plane was still in the air. This isn’t a new phenomenon, they’ve been around for as long as I can remember!
This would be in the 70s. Yes, the skies around Pittsburgh weren’t THAT bad. You have to remember that the Steel mills were starting to shut down and the air quality started to improve.
I have been looking at blue skies for over 60 years. I can remember looking at a certain amount of contrails all my life. The sky was blue and I mean blue and sunny on a summers day. 15 years ago I started working what I call vampire hours. I slept alot of the days away and up about all night. I didn’t get to see much of the sky. This past year I have found myself unemployeed like so many others. I would get up in the morning to a nice spring or summer day which didn’t last past 10 am. I kept wondering what had changed I knew something had. Some days I will see contrails going in all directions within an hour the sky will be like a sheer white veil and never see the blue and sunny sky again. … I really miss my nice mornings and sunny skies.
I’ve been around for a while, now, and here in the inter-mountain west and the northern high plains I see no difference in the behavior of contrails. There are certainly MORE of them than in the 60′s and 70′s but they act the same as far as I can tell. And you can see a l-o-n-g way from a mountain top!
I’m 50, from Indiana US. I remember contrails just as they are today from my childhood. I had an interest in the planes over my head because my father commuted by plane for most of my childhood. There is always the wonder if Dad is in that plane over head. There are absolutely more planes now.
I was in the USAF from 1990 to 1996. I remember having a guy come into our unit that had a BS in aeronautical engineering, but he was enlisted. I was amazed that he didn’t apply for OCS since he would be able to. Anyway, me being a guy who didn’t have a BS I thought he would be a wealth of knowledge for the many questions I had. (there was no Google back then) I asked him why some contrails lasted a long time and why some went away quickly. He didn’t know. Now either he didn’t pay attention in class, or they didn’t teach him about that, but it doesn’t matter. I clearly remember being interested enough to ask this question in the early 90′s. Being 43 now, I have a hard time remembering what I had for breakfast, but that one memory seems to validate that persistent contrails have been around for a bit.

I always see people making comments that these are just planes on their regular flights, so how is it that they are doing these "curved" lines in the sky, and this was two or more planes flying in pretty close formation.
People really need to start thinking outside the box, this is not NORMAL by any means.
Have you ever heard of a holding pattern?
And yes, this is quite normal, even though it is generally avoided when possible, but it still happens. How's that for thinking outside the box
That explains why I've seen them curve no where remotely near an airport...right?

I would like to put up a picture in defence of the OPs thread, this picture was taken in Los Angeles Ca on 4/18/2012, what this shows is at least 2 planes making Chemtrails/Contrails that are curved.

I've also been running a survey of when people first noticed persistent contrails, you can see the results here:

I pointed this out a long time ago. There were no lines in the sky when we were young. Not even when I was older. Not even 4 years ago!!!
Here in South Africa, they started spraying in 2010.
So, how is it that in this modern age, all of a sudden there appear lines in the sky that never where there before??
Eyes wide shut.......

I think you may be missing the point here. He didn't say planes didn't create contrails before, because they did.
What i'm getting is that planes didn't leave trails that lasted for several hours and covering a whole area for the rest of the day.
"Contrail - streamer of cloud sometimes observed behind an airplane flying in clear cold humid air. It forms upon condensation of the water vapor produced by the combustion of fuel in the airplane engines. When the ambient relative humidity is high the resulting ice-crystal plume may last for several hours. The trail may be distorted by the winds and sometimes it spreads outwards to form a layer of cirrus cloud." - Encyclopædia Britannica 1993.

Do you really need someone to tell you how ridiculous your statement is ?
It does'nt matter how many planes !
If they were 'normal' contrails they would dissipate at 'normal' rates, not linger !
Peace
As measured later (1969) by lidar the mean thickness of the contrail sheets was 500 m.
LiDAR (also known as LaDAR ot Laser Detection and Ranging) has been used extensively for atmospheric research and meteorology due to its excellent resolution. It was only with the deployment of Global Positioning Systems (GPS) in the 1980s, allowing the precise positioning of aircraft, that LiDAR made airborne surveying possible. Since then many downward looking LiDAR instruments have been developed for aircraft and satellite use.
Again, contrail persistence is assumed...If we further speculate that deeper cloud cover would occur on one out of every three days in both cases...

Uncinus (debunker), you are exactly wht i am talking about, you claim to be a "Debunker", which implies, you know enough about everything to be able to "debunk" whatever you want to.
When in fact the truth is, all you know is what you have "Learned", all you do is spew the set of information that fits best with your precepts and inate naivety.
You don't "Debunk" anything, you just regurgitate information in defence of precepts you have no idea of knowing one way or the other if they are fact, this is due to you "precluding" any kind of "strange" or "odd" information that is outside your spewing capability as requiring "Debunking" because that is all you are capable of, irrespective of the facts.
I just denied your obvious, blatant, and well maintained ignorance, Debunker indeed, don't make me laugh.edit on 3-5-2012 by The X because: (no reason given)edit on 3-5-2012 by The X because: (no reason given)
