What makes me wonder is that if these were normal contrail they should not all have abruptly appeared at once, but have been visible following behind the jets as they approached. But I must say they didn’t linger, and the sky did not haze up, as I hear is characteristic of chemtrails. And the weather here has been very cold which I imagine is conducive to the formation of your normal ol’ icy condensation vapor trails. So once again, I don’t know what is going on. But this new camera is light enough to take with me everywhere. I’ll keep my eyes open for any further clues.
