I have used balloons, and high power rockets with pidot tubes and have found nothing but the normal atmospheric components. I have done this over a dozen times and in my opinion chemtrails are a total myth.
Please explain in detail your techniques used for sampling contrails.
What will the "pidot tube" determine and how was the sample retrieved?
Sounds like a false statement to me, but I will reserve judgement so can provide more information to support your statement.
Did you mean Pitot tube?
A pitot ( /ˈpiːtoʊ/) tube is a pressure measurement instrument used to measure fluid flow velocity.
Aircraft use pitot tubes to measure airspeed. The example in this photo combines a pitot tube with a static port and an angle-of-attack vane. Air flow relative to this device is right to left. The pitot is the pencil point shape and the vane is black.
