That is the norm but under the right rare conditions they might last five or even more minutes.
According to someone else they last 30 seconds
Oh, and theres no reason why contrails can't persist. None.
Which is one again not unexpected but should be far rarer than we observe it to be.
Well it isn't.
Why would so many thousands of people send emails or letters to their representatives about this phenomenon?
Because they're idiots?
Joke
I honestly don't know.
Who said that the equipment have to be installed
Me, because they're definately not installing it at factories.
or that it is large?
Because you're going to need a large tank to hold the chemicals.
Who suggested this operation uses commercial planes at all?
The person who said a KLM 777 was chemspraying
This
guy
And mechanic email. The page has since been deleted.
I know you want to debunk the whole thing as fast as possible but try stick to theories at least proposed?
There is about 50 chemtrail theories, all containing diferant things.
As i understand it these materials would just be mixed with the fuel itself if the operation were to be carried out by commercial planes
What materials are in chemtrails again?
Which would be a silly way to go about installing equipment you do not want people to know about?
How do you think they installed them then?
Do 'debunkers' like yourself choose the most illogical way to keep a secret operation mostly secret by chance or do you do it out of shear
spite? If you do not understand the notion of conspiracy do some research and discover what types of massive conspiracies are possible and have been
perpetrated in relative broad daylight.
Lay off the insults, whether they were meant to be or not.
If there were holes to see and if these people would know about them why assume they would tell us?
Because they're people, and they will do that. If you see spraying equipment and you didn't know what it was, would you tell someone? Probably.
I've also had various people breach NDAs just so I could have a go of some alpha software. With a few thousand people with something as serious as
chemspraying equipment / holes in aircraft there WOULD be leak.
"Federal" sums up everything you should know so don't lecture me on what they might know and what they are allowed to disclose to you and
me.
So what? Huge amount of civialians work for the FAA.
but they most certainly do not and that has nothing to do with what they are allowed to disclose publicly.
Once again you focus entirely on the civilian aspect as if that is the main thrust of my argument; why?
Because it's the worst claim I've seen in my entire life, and the amount of ignorance involved in the civilian aspect is amazing, which makes it
very annoying.
I find that people working in fields they love are actually more easily bound by secrecy as they are even more unlikely to risk their jobs.
Yep, I'm talking about the civilian aspect here. Mechanics involved with jets don't have to sign any NDA, same with pilots.
The assumption that my interest and belief in strange long lasting contrails stems from looking at a few pictures leads me to believe that you
consider my absolutely foolish and probably stupid.
Not sure if I get this, but I don't think you're foolish or stupid.
All i have seen so far is you appealing to convention and generally suggesting that since you can not imagine a conspiracy there can't be one
while going about attacking claims i never made or even supported.
Laymans terms please?
Do you think someone needs to be a aviation expert to realise that contrails that rarely lasted more than a few dozen seconds should not
suddenly a few years later last many hours or even days?
Contrails usually last for over a few dosen seconds, and theres no reason why contrails cannot last for hours. None.
At least i have been rather specific in calling only one person deluded and disrespectful while you have used a far broader brush for hundreds
of thousands of Americans.
What about Americans?
Well you should have said you 'will attempt' but this that statement was as revealing as anything more specfic.
I typed the entire thing up twice, each time the power went off. So I did attempt it.
Those would not be very smart pilots as they would have to assume that their flight plans are wrong. What about their cockpit would they be
monitoring that would not have a sound or light cue to indicate noticeable deviation from the set norm? I am no expert but what i have described above
seems to be norm in the books and material i have read....
Yes, Pilot are constantly monitoring the cockpit, the aircraft, and aircraft around it. When at the gate the pilot(s) use the
CDU to enter in the route. And no, in planes I am familiar with there is no alarm that
signals if you're off course, though, a plane being off course never happens unless the pilot does something stupid.
TTCAS does however, have aural warnings.
And you will do this by staring out the cockpit window in your opinion? This is most certainly not the impression i got from what i have
read...
ATC,
TCAS and the pilots eyes all assist in looking out for traffic.
And light aircraft are also very unlikely to fly at the altitudes normally associated with contrail formation....
But it does demonstrate that pilots NEED to be situationally aware 100% of the time, and in doing so they may occasionally see UFO's, and would most
definately pick up on commonly seeing KC-135 tankers flying around with contrails that were longer than anything they've ever seen before (which
dosn't happen).

That being said being worried and paranoid
about things completely beyond your control can make you physically sick if you do not deal with such worries in the correct fashion. Our bodies
respond to the way we think about the world and a negative defeatist attitude will most certainly impact your health negatively and do so even in the
very short term so it is extremely important not to worry about things that you are not actively addressing in constructive ways by planning or by
physical action.
