Several years ago, on 2017/08/23, a photographer walked out to see six suspicious small planes in the sky over Long Branch, New Jersey and started to record them when, in the blink of an eye, a fast-moving object flew by right in front of the camera's lens.
According to the terrified photographer he was ducking and flinching as it flew past and could not believe what he witnessed.
We can rule out that it would be an insect or bird that flies by just in front of the camera lens as the slow motion footage shows the object moving away from the photographer's location at a high speed until it disappears. Mufon.
