In the English city of Welwyn Garden City, located 30 km from London in Hertfordshire, on April 3, 2017, several interesting anomalies were caught on video (see video below).
A down-to-earth local named Stephen Clementson installed a surveillance camera at the wheel level of his car. You must admit that this is rather strange, but it was precisely this position of the camera that helped to catch the troublemaker diving in the parking lot.
Video captured by the surveillance camera shows an object in the form of a long beige cylinder with helical blades emerging from the bottom of the screen and continuing to fly diagonally to the left.
Apparently, the anomaly was moving at high speed, so Steven had to take the video out of frames to understand what this strange UFO was doing at the wheels of his car. But the beige propeller wasn't the only one interested in wheels. A few minutes later, another helical object flew out from the same corner, but thinner and more flexible, which bent in flight like a nimble lizard and flew out of the camera to the right side.
Who knows, perhaps the observation of just such objects could have prompted the ancient Greek mathematician and engineer Archimedes to create his famous screw.
