So, for many years, despite being totally red pilled on pizza gate and a million other things, I still thought the chemtrails theory was suspect (like flat earth is suspect). I felt that the explanation was reasonable that at certain altitudes, temperatures, and humidity levels, contrails could linger for extended periods of time. But, about 3 months ago, instead of a few lingering contrails here and there, it's ramped up to dozens of them almost every single day. After these days, the evening and overnight winds are insane. We've had insane winds most days for MONTHS. Never experienced anything like it in my life, completely ridiculous to pretend it's a natural weather pattern for the region I live in.
So, coinciding with the dramatically increased and regular "lingering contrails", I thought to myself 'I guess I should look into this chemtrail thing a bit.' So, I watched the documentary "What In The World Are They Spraying?" and they presented evidence about astronomically high levels of aluminum in the soil in places where they do this spraying, which causes the PH of the soil to come way up, so I decided to test the soil in my own back yard. Predictably, its PH is WAY high at 7.9. At 7 a lot of plants can't survive have trouble.
Anyway, I'm now thoroughly convinced they're spraying something for some reason, and obviously not a good one. So, I've been paying more attention to what days they spray, and if I could spot a pattern. I've logged in to flight trackers to try and figure out which planes, and I've searched on the internet trying to find others who have already spent years trying to spot the patterns of these flights... But I couldn't find much. There are several websites with a LOT of surface information, but apparently no one has simply logged the days, amount of passes across their airspace, the flight numbers and callsigns (or lack thereof) of the aircraft, and compared these datasets to possible explanations. If any of you know of a place where such data is compiled or presented, I'd love to see it.
Now then, I've hit upon one data point in a possible pattern: after months of total sky covering spraying almost every day, there was no spraying at all across the entire Memorial Day weekend. There are plenty of standard passenger flights across this weekend, the sky was full of planes like it is any other day- but no lingering contrails. Not a single one. Do we ever see lingering contrails spreading across the sky on federal holidays? If not, that's quite a damning coincidence. If we could demonstrate a pattern like that, we could easily shut down the "lingering contrail due to common atmospheric conditions" argument- does the weather take federal holidays off?
Actually, I did. I posited 400mph for 1 hour. Please make me smart because 30.5 miles of the earth would drop from under the plane if it did not nose down the entire time. There is absolutely no way a pilot could nose down 30.5 miles over the course of 1 hour and not notice a consistent and persistent downward motion that HE would have to be constantly performing when not on autopilo. It would not just be smooth, it would require real work. This is common sense; something incredibly lacking in the most educated in our society. It's like the universities, no matter the major, make arrogant or at best, overly confident people; so sure in the knowledge they were taught by their elites, that questions are taboo. Even the most humble of the highly educated appear to believe the nihilistic version taught in western universities. Lacking is nuance. When one believes they already KNOW the answer, their mind immediately closes. So sad. There is so much to learn and explore if you escape their grip.
I told you, but you didn't understand. There is no change in altitude. The airplane is designed to fly "level," which means it aligns its vertical axis with the local vertical---which is the local direction of the gravity field. This happens without any pilot input, and is driven by the continuous shifting of the local vertical as the airplane progresses horizontally. This produces a slow pitch-down motion, matching the curvature of the Earth. If I have done my math correctly, this will be a rotation rate of 0.000265 rpm. By comparison, the Earth's rotation rate is 0.0007 rpm. Since nothing changes visually, it is unnoticeable. The pilot can be asleep and this is accomplished by the airplane longitudinal stability design. (In fact, there are cases where pilots have died in their seat and the airplane continues on heading and altitude until it runs out of fuel and crashes.) Sometimes, the design can result in a poorly-damped roller-coaster motion called a "fugoid oscillation."
Your "common sense" is contrary to the engineering of airplanes, and you need to learn what is really going on. I can play your own phrase back at you: "When one believes they already KNOW the answer, their mind immediately closes." This is you. Your "common sense" is wrong.
In the case of very high speeds (e.g., hypersonic aircraft) there will be an increasing centrifugal effect counterbalancing the weight of the airplane. In the limit, it is a perfect balance and the vehicle becomes an object in orbit.
