Unfortunately I can only imagine what your videos will be edited into. I wouldn’t be surprised to see them crop up in “chemtrails exist!!!!” videos. I can see people making out you’re a concerned pilot who has started videoing this phenomena in an attempt to let the public know that they are being sprayed.

And here it is -> http://www.youtube.com/watch?v=9yrj_NTP2Vw

Recognise any of those videos, captfitch? Not saying they’re yours, although there might be a bit in there.

Like I said- it’s complex.

Here’s an example:

If I need to go from DFW to HOU I start by planning. There are at least two or three different departure procedures (DPs) I can choose from to leave DFW. They terminate at several points that are in the direction of HOU. HOU has at least three arrivals that begin around the DFW area. I can pick one of those and connect it with the departure from DFW. Now I have a full route that I trhow into the ATC computer. But the ATC computer looks at my route and either likes it and keeps it or gives me something totally different (or slightly different) and now I’m expected to plug that into my plane and fly it. The ATC computer knows everyone who wants to fly anywhere near your route and adjusts those routes to a degree to provide the smoothest flow. Controllers can intervene at any point and change that route before or DURING the flight to suit thier needs.

Additionally after I’m in the air the sky is literally the limit. We can move left and right, up and down for many reasons (weather, traffic, better rides, better winds) OR JUST BECAUSE WE FEEL LIKE IT!!

And yes- i would say that with a few exeptions (like very deep into an arrival or on a very popular route like J6 that runs back and forth to the East Coast) that there are soo many variables that virtually every flight will vary with some degree even more than slightly.

Let me start by saying that with very few exeptions you can fly from point A to Point B ten times and never fly the exact same route. Obviously the longer the route the more possibility for variance but the same holds true for short routes as well.

It’s really too complex to get into but the bottom line is this- NEVER let a chemtrailer tell you about “normal” traffic patterns. If you told me I was going to fly from NY to LA I can tell you what I would like to fly and what I might expect to fly but I could never tell you what my route will eventually be.

Uncinus- Again, very complicated but yes, I have flown through my own contrail.

Here’s the problem with this scenario and why it’s rare: As you know by now persistant contrails typically occur in advance of some upper level system that will bring bad weather to an area. The weather under persistant contrails is usually nice so traffic into and out of those airports is usually not backed up. We almost NEVER hold at altitude but here is when you might do it: In the summer there are often squall lines three or four hundred miles in advance of a cold front associated with an upper and lower level low. These lows pump moisture high into the atmosphere, causing contrails. If the squall is slow-moving (usually in mid summer) the line may take hours to pass through an area like DFW. We may be inbound to DFW and the squall may back up traffic far enough west to get into an area condusive to contrail formation and we may be high enough stil to make them in our holds. (these holds could last for an hour and we may do 8 or 9 turns around the holding fix) The ones that can fly high are held up high to make room in the stack for those that can’t, so the stack may be twenty-thousand feet high with twenty planes in it.

So here we are in the hold making all sorts of persistant contrails but ther is one more problem. What the CTs claim to see sometimes is the “chemtrails” dripping or falling. They ARE! Anything we produce is pushed down because of Newtons 2nd or 3rd law (I forget). They initially fall at about 1000 feet per minute and then slow to a stop after about ten minutes. So by the time you make it all the way around to where you’ve been the trail you made earlier has fallen out of your path. ONLY if you descend IN the hold can you fly through you’re own path. BUT- they usually turn you out of the hold before they let you descend so you don;t hit anyone below you in the stack. So you see it’s rare- but I have done it.

Another thing, holds are usually predicated to some degree on what the pilot wants. It may show on the map one way but if we prefer to hold with left-hand turns instead of right they can let us. And if we want to hold in ten mile legs instead of minutes we can usually. It’s up to ATC to let us and they usually do. Again- there is NO SUCH THING as NORMAL traffic patterns.

Next question?

That’s a pretty rare contrail pattern, so I was wondering if such holds actually happen to regular traffic – or would it most likely be training/testing/military?

I hope that question makes sense, it looks kinda cryptic when I read it to myself lol.
