that doesn't appear to me to be the same thing as the multiple planes doing the crisscross patterns. this thread is long and i haven't read it all, but has anyone explained the difference between one plane with a con? chem? trail behind it as opposed to 2 and sometimes 3 crisscrossing over the same area for hours?
As a 20 year fighter pilot I can attest to his offering regarding fighter pilots getting the meteorological info of where "the cons" will be before stepping out to fly.
In the USAF the brevity term for being in the cons was "Marking", as in "Conan 2, bring it down, you're marking." As we entered the MOA or Warning Area to set up for a practice long range fight we'd have one of our wingmen "light the cans" and climb up to check it (the weather liars aren't always entirely accurate). As soon as he started to "mark" in the climb, one of the other guys would call "Marking" to clue him to report his altitude as you can't see it easily from the cockpit itself (they start a few hundred feet directly behind you usually).
Conversely, as he climbed out of the cons, a flight member would call "Stop mark", the reply,"340." Armed with that info, when "committing" out of the CAP, we would go min burner (to save gas) to climb up through the cons above 34,000 so that the bad guys couldn't see us as we approached them from 60-70 miles away.
This also serves to increase the range of your missiles as you get faster and higher up in the thinner air, and as well your fuel consumption is significantly less at altitude.
Typically, the cons will begin in the mid 20s and end in the mid to high 30s, but they can stretch up into the 40s if atmospheric conditions are right - I had a wingie marking at 49,000 at Nellis once (very rare) when we (Alaska F- 15Cs) were trying to set up a difficult 3 group "Hi-lo stack" problem simulating MiG-29s against heater only armed F-16 students and IPs from the USAF Weapons School back in '93 (I was out of them at 52,000).
Six of us against eight of them, but four of theirs were bomb laden strikers. The problem was very difficult - we slaughtered them and the poor student leading the mission had to re-do the ride.
They initially saw my wingie in the high cons and got overly concerned with him and thus didn't see a lower Eagle who'd done some good maneuvering with chaff. He ended up 15,000 feet right over the "battle box" of the 4 strikers down in the weeds trying to hide behind mountains as they ingressed to their target. He "popped" all four as he dove down on them in less than 30 seconds then added insult to injury by gunning one of the other Vipers only minutes later - a simulated "Ace in a day".
So are you still trying to sell the idea that the high altitude aircraft leaving the small contrail in the video was actually flying lower than the aircraft that left the huge chemtrail?
all i'm trying to sell is a rational approach to this controversy.
if there's a mystery, we have to start somewhere, dont we?
and the first place to start is: finding out if there's really a mystery at all.
so far, everything you guys have posted has been completely lacking in facts... so nobody can tell, from what you've posted, if there's a mystery or not...
...not only that, but everything you've posted can be explained by the laws of chemistry and physics that cause contrails, so we dont have to trot out out this "chemtrail" baloney at all.
so the burden of proof lies with you ...you have to come up with evidence of an existing "chemtrail" that cant be explained by the chemical and physical science of contrails...
so far, you've failed miserably to provide proof of anything except your gullibility and bullheadedness.
Did you watch the full video BTW? The lower trail is VERY low on the horizon, MUCH lower than a high altitude trail would be, where the high altitude aircraft is significantly higher in the sky than the lower altitude trail, which arcs down under the tree cover while the high altitude jet is far above it.
the altitude of the sun is supposedly 93 million miles, and once or twice a day, it comes pretty close to the horizon.
Well there's water in the ocean too, but that doesn't mean I'm swimming in it right now.
Man, you are a master of obfuscuation aren't you...
The fact is, we are not talking about the sun, we are talking about TWO trails in the sky, one being left by an aircraft that MUST be at a higher altitude than the larger trail due to its position in the sky in relation to the horizon and to the larger trail.
Just from your tap dancing it's obvious you're not interested in really finding out the facts, you're here to confuse whatever facts we can determine.
I'm surprised you're not trying to claim the contrails are actually formed by starships, since we can see stars, and those stars are in the sky.
Is the sun a seagull? If it were, then the seagull would be higher, but since it's not, then it's an invalid comparison.
The fact is, the video shows TWO TRAILS, which YOU claim are BOTH normal CONTRAILS. Since you claim that they are the same phenomenon, then it IS a valid comparison to make between them.
Do you think the earths rotation would have anything to do with these contrail patterns? Since they are aiming for flying over / to fixed points on the earth, and the earth spins more or less independently from the atmosphere, then you will get parallel lines and X intersections.
Do you think the earths rotation would have anything to do with these contrail patterns?
Moving objects on the surface of the Earth experience a Coriolis force, and appear to veer to the right in the northern hemisphere, and to the left in the southern. Exactly on the equator, motion east or west, remains (precariously) along the line of the equator.
Movements of air in the atmosphere and water in the ocean are notable examples of this behavior: rather than flowing directly from areas of high pressure to low pressure, as they would on a non-rotating planet, winds and currents tend to flow to the right of this direction north of the equator, and to the left of this direction south of the equator. This effect is responsible for the rotation of large cyclones
looks like coriolis causes the wind to curve, so contrails embedded in the atmosphere would curve along with the wind.
i dont know if it happens on a small enough scale that you'd be able to spot those curvatures from the ground, though... this judging from satellite photos of persistent contrails, which seem to be straight... if a long contrail persisted long enough, maybe we'd be able to see some curvature from space.
or maybe the rotation is so massive that a contrail embedded in the air mass stays straight.
I dont think we are writing about the same thing here. I'm not writing about curvature.
Say you are flying from KC, MO to Houston. That is more or less north and south. You take off at 9am.
Another plane takes off at 9:30, same flight plan.
The earth will rotate X distance, west to east, in 30 minutes.
To my way of thinking you will have parallel contrails with those 2 planes. The planes fly over the same ground, but not through the same atmosphere since the earth and the atmosphere are more or less independent. This would lay down 2 parallel contrails X distance apart.
Another reason for parallel trails, if 2 planes are flying together, is in keeping proper distance between aircraft heading in the same direction.
the independence of the earth from its atmosphere is measured as wind velocity.
I can see that being a factor, but is that an absolute statement of fact? Wind velocity also has to do with high and low pressure systems etc.
OK, my example of 30 minutes would be too long in my example, using your pic, even though the pic is of parallel contrails according to the file name. Perhaps 5 minutes or less would be better.
The more east/west you fly the tighter the contrails would be.
Thanks! Once I really get into this, I realize how much I don't know about weather etc. It's an interesting science.
it was hands down the most universally despised subject in flight school.
it's complicated and it's boring...
...and for a helicopter pilot who is the next thing to a john deere tractor driver, it's useless... mainly because helicopters are working under the weather, and your forecast consists of getting up before daylight and looking out the window to see if it's raining or blowing or snowing too hard to work.
