So the other night I was out with my fiance and 2 friends at a festival in Fort Langley (in the lower mainland of BC Canada) when out of nowhere we all, with other people, saw several lights in the night sky that were flying erratically.... how it caught my attention ...it started off with just one light, which I just thought it was a plane or helicopter (but no blinking lights), that went up....hovered for a bit, moved to the side, hovered again and then disappeared...several other lights came out soon after and made the same (almost) flight pattern... all I can say is I was intrigued of what they could have been...
