About 15-20 minutes into our flight I noticed what I thought was another plane and all of the sudden whatever it was did a 180 without losing altitude or speed. I can only see two contrails but no object.
I was shocked as I'm a flight attendant and have never witnessed anything like this before and my husband also saw it and he flies every week for the last 25 years and has never seen anything like it.
I have shown many others, commercial pilots included, and they also have no idea what it could have been. The stills I have included are stills that I took from pausing the video.
Note: Just today I posted an article about Project Blue Beam and fake holographic-cloaked planes and I think this video is an excellent proof that fake planes exists.
