Quick guess would be this:

Do you have access to the original photo? If yes, could you please post its Exif?

My educated guess is these three flights:

As the middle plane was at a lower altitude of 32,000 ft than the other two (at 36,000 ft), the three planes would appear more evenly spaced.

Thanks for the help, I will try to get the EXIF data from the person who posted it.

Interesting to note, the contrails do not appear to be persisting...in case people were claiming "chemtrails".

Could it be a military flight? This footage is from Petaluma which is to the north of Palo Alto and San Francisco.

I caught this footage over Petaluma, CA on March 14th 2017.

I assume you mean 10:30AM PDT? i.e. 18:30 UTC?

Seems too far away, about 100 miles there.

Shouldn't be a problem for long lenses, unless hidden behind local geography. This is one of the reasons I requested Exif.

The other is that I suspect this is a 'trick' shot - an overlay of three sequential shots of the same contrail. Deflected from the plane track by wind, such a multiplied contrail makes a series of staggered parallel lines. I've seen this technique before, for example:
