Are you in Washington state?
Anyways... They were going balls to the wall what I filmed. There was as much as 3 planes in the same sky at the same time making X-patterns and grids.

If this wasn't occurring like clockwork with the same effect occurring I would not think anything odd was up. I have noticed this occurring often.
I thought I made it clear that I AM NOT SAYING THESE ARE "CHEMTRAILS" That would be silly to assume that there is chemicals in them, how could I possibly know that?
Contrails ( /ˈkɒntreɪlz/; short for "condensation trails") or vapour trails are long thin artificial clouds that sometimes form behind aircraft. Their formation is most often triggered by the water vapour in the exhaust of aircraft engines, but can also be triggered by the changes in air pressure in wingtip vortices or in the air over the entire wing surface. Like all clouds, contrails are made of water, in the form of a suspension of billions of liquid droplets or ice crystals. Depending on the temperature and humidity at the altitude the contrail forms, they may be visible for only a few seconds or minutes, or may persist for hours and spread to be several miles wide
. Persistent contrails are thought to have a significant effect on global climate.

Interesting, thanks. So even contrails are dangerous and potentially altering the environment....
I am wondering what kind of atmospheric conditions need to be in place for contrails to stay visible for over an hour an disperse in a grid?
If you are attentive to contrail formation and duration, you will notice that they can rapidly dissipate or spread horizontally into an extensive thin cirrus layer. How long a contrail remains intact, depends on the humidity structure and winds of the upper troposphere. If the atmosphere is near saturation, the contrail may exist for sometime. On the other hand, if the atmosphere is dry then as the contrail mixes with the environment it dissipates. Contrails are a concern in climate studies as increased jet aircraft traffic may result in an increase in cloud cover.
So even contrails are dangerous and potentially altering the environment....
When I mention the grid pattern I do not mean the crossing of separate trails. The grid pattern in within the trails themselves:
A mackerel sky or buttermilk sky is an indicator of moisture and instability at intermediate (altocumulus) or high (cirrocumulus) levels. The phrase 'mackerel sky' came from the fact that it looks similar to the markings of an adult king mackerel and this phrase is generally only used if a significant proportion of the sky is covered in altocumulus or cirrocumulus. This usually produces perspective effects as the clouds become smaller towards the horizon. Mackerel skies are spoken of in the popular bywords, "Mackerel in the sky, three days dry," "Mackerel sky, mackerel sky. Never long wet and never long dry," and the nautical weather rhyme, "Mare's tails and mackerel scales / Make tall ships carry low sails." In the winter they are often said to precede snowstorms and flurries. Mackerel skies have therefore become synonymous with bad weather approaching. However while altocumulus does rarely form instead of the more usual altostratus ahead of a frontal system, it is more likely that a so-called mackerel sky signifies the break up of an altostratus layer and leads to brighter conditions, and so the forecasting value of mackerel skies often depend on whether it was cloudy or clear prior to their appearance. However even if it was clear prior to their appearance, it does not always mean rain is approaching as altocumulus is often associated with a weak frontal system where the usual altostratus has become broken, and in this case there is a chance the weather may remain dry, although it is more likely that there will be light drizzle from stratus clouds.
