Four aircraft circle like vultures then shoot off at great speedsI was watching a plane dump out a chemtrail when I noticed what looked like four "vultures" very high up in the sky. They were at the very least 4000 ft in the air, yet their shape was quite visible, and unusually large. They made unusually quick circles for several minutes, then I finally decided to try and film them with my iPhone; and as if it was scripted I kid you not they stopped circling and shot off at an insanely fast speed, one by one. Of course the noon sun made it impossible to capture via the iPhone 5s, but my eyes (shaded by raybans) saw everything in 20/20 vision. I wouldn't waste our time with a fairy tale, this was a unique event.
