Bright v-shape light coming from behind a quick-moving craft

Around 7:40pm on Saturday night 9/24/22, I went to close the blinds in my room and witnessed a strange moving light in the sky. Not a plane, as there was a plane in sight too, going a different direction, but this looked very different. This was only one prick of unblinking light moving in a straight across the sky right to left as I looked from my window (Eastbound). The pinpoint of light had a thick v-shaped very bright white light beaming out behind it. I had my dad get up to look at kitchen window then we ran to the backyard to see. There was no sound coming from it. We watched it as it was for a few moments continuing straight and relatively fast on its path, then all of a sudden the light beam seemed to detach from the craft and was left behind hanging in the sky as the prick of light continued on. Within a few moments, the prick of light wasn’t visible at all and as the light beam faded too, it was like it was never there – nowhere to be seen. My dad and I were flabbergasted and agreed that it was very odd, especially the way the light suddenly detached from the craft itself and was left paused in the sky while the craft continued on, only to fade out some moments later along with the visual of the craft itself. Very strange and notable – my dad and I had never seen anything at all like it. Both of us have a familiarity and somewhat casual academic interest in UFOs, and could not identify it as anything UFO or non-UFO that we are familiar with in the sky. Could not obtain any video footage as neither my dad or I have a smartphone.
