Contrails (short for “condensation trails”) or vapour trails are artificial clouds that are the visible trails of condensed water vapour made by the exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets. If the air is cold enough, this trail will comprise tiny ice crystals.
First, it was that travelling blue light thingy in the night sky over Centreville, Virginia, just above Lee Highway. Many shoppers saw the strange light for 10 minutes, including Bryan Fains who quickly grabbed his cell phone and captured it on video.
Fains said, “All of a sudden, it would stop and go back like this,” using his finger to point out the direction of the blue light in the sky. “At one point, it stopped and went up and up. [There] was no sound. It was a distinct blue light. It never flashed or blinked or nothing. It was just blue. It’s weird. You only see this type of stuff in movies.”
Then, it was that missile-thingy launched into the sky off the coast of southern California last Monday (November 9). KCBS news helicopter cameraman Gil Leyvas videotaped the missile plume at around 5 pm PST at the height of evening rush hour. The Pentagon says it’s just contrail from a jet aircraft!
Yesterday (November 11) at sunset, this bizarre, glowing red-hot streak in the sky was seen moving briskly behind the Manhattan skyline. CBS 2 asked an unnamed “top astronomer” to look at the video. He said it looks beautiful, but that it was nothing more than a contrail from a commercial or military jet!
Move along, folks. Nothing to see here. It’s all contrails!
