First UFO? A light in Calgary’s night sky

A Reddit user’s clip shows a single point of light in the night sky. The person who posted it says they filmed it in Calgary on May 11 at 10:17 p.m. They report hearing no sound and say they could not identify the object or find it on flight-tracking radar.

The image does not show enough detail to establish what the light was or independently verify the sighting. The question in the title remains open: the clip records an unidentified light, but does not establish that it was an extraterrestrial craft.
