A contrail starts and stops the same way a cloud starts and stops; the air has layers and turbulence, and air in different streams may be more or less amenable to contrail formation.

In regions of saturated air, moist exhaust gas from the aircraft will form contrails, as the water turns from vapour to ice. In those areas of the sky where the air is not quite saturated, the exhaust gas vapour will remain in gaseous form, which is invisible to the eye. If a jet is flying right at the boundary, stuttered contrails can occur.

The key phrase here is all things being equal.

Two planes in the same part of the sky at the same time are almost certainly not flying at the same altitude, the standard is a minimum of 1,000 feet of vertical clearance between planes.

ice... so when it spreads out and covers the entire sky... thats all ice... so California drought was in the sky... "ice" all they needed was for it to melt..


here the real story...

Wink You could make the argument that Monthly Weather Review has been complicit in the conspiracy since 1921

The earliest public report of persistent, spreading contrails with gaps appears a few years after the first public documentation of airplane contrails from high-altitude prop plane flights.

When the airplane reached a height of 26,000-27,000 feet at 11:50 a.m., a long feathery white streamer was observed forming behind a rapidly moving dark speck. The cloud was of the cirrus variety, well defined at the edges and apparently 10 to 15 times the width of the plane. The sky behind the first portion was clear blue with no clouds in the near neighborhood. The first streamer seemed perhaps 2 miles long. Then a gap of one-quarter mile. The second streamer formed with a background of light cirrus cloud and after 2 or 3 miles the plane seemed to go into the cirrus background, for the streamer formation ceased while an apparent path of blue continued beyond for a way in the cirrus cloud. The whole streamer may have been 3 miles long. After 20 minutes the streamer had drifted and spread until it merged indistinguishably with the other cirrus clouds visible.
Since you probably don't have an original copy of the US Air Service Newsletter lying around for reference, both of the above were reprinted in the June 1921 Monthly Weather Review.

Rain happens when ice crystals (called nuclei) grow using water vapor in the air, splintering into more nuclei which also scavenge the water vapor for growth, and eventually they all become large enough to fall through warmer layers of air and become raindrops. This is called the Wegener–Bergeron–Findeisen process.

If there isn't enough water vapor in the air, growth doesn't happen and you don't get rain. That's why sometimes when there's cloud cover it rains, and other times it doesn't rain.

reality says, one has a switch.

if there was no switch... then the nozzles can get plugged?? to cause it to go off and on..

That should be the other question... how can it start and stop... in mid air..

Nope, they would have to be in the same position, the same size, the same wind of the same temperature impacting them at the same moment, the same position for the observer due to the light refraction being required for observation etc etc. There are a huge number of variables, going way beyond "two planes in same sky" simplistic nonsense.




And what about natural contrails which HAVE to exist sometimes. Do you see double chemtrails and contrails?




You just gloss over it to fit what you want to believe. Its "them."

Here is a photo of the "chemtrails" we used in World war two. I guess they wanted to get good coverage by not flying straight?
