Blue By You? Colored Contrails Conundrum

IMG_4030blueContrail480
This picture with my iPhone was taken outside Schoolhouse Fabrics in Floyd.

The first time I saw a metallic blue contrail I thought it was just some odd play of light at that particular angle and time of day.

The second time I saw blue razor-thin lines across the sky they existed alongside of the usual white contrails, with the two planes at similar altitudes, normal-looking passenger jets I supposed, visible as they created their tracks across an otherwise cloudless deep-blue sky.

Over the past few months, I’ve seen this maybe a half-dozen times. Ann was with me the last time when we were gathering firewood along the creek. She had no trouble telling that we were looking at distinctly blue contrails.

I have not been able to find out anything to explain if this is a new type of engine, a new type of fuel or if the chemistry of these non-white vapors has changed in other ways.

I’m surprised not to find the chemtrails conspiracy folks all over this. Surely it’s not just the two of us on Goose Creek that see these blue streaks. Anybody else seen them? Any clues as to why they have appeared in the last few months?

  1. No clue! Your photo doesn’t make me sit up and say whazzup. Maybe if i had been there. I just assume that the amount of condensation is light enuf to not make a bright white “cloud,” and the thinness of the vapor trail is allowing the blue sky to show through.

  2. I don’t think this explains it. I’ve paid attention to hundreds of contrails as a cloud-watcher. And there were contrails at the same time and the same altitude (judging from the comparable size of the jets involved). Only noticed blue in the past six months.
