I was getting some fresh air behind fleetwoood's in asheville, nc on a cold night. i was looking at the sky (i've had other ufo sightings so i keep my eyes up reflexively) when all of a sudden a triangular shaped formation of forward pointing chevron shaped objects appeared glowing through the clouds. there were five on the right side and four on the left - what would've been the third was missing from the formation. the had matching lines on them, like seams. it was odd that i could see these seams as the objects were as far away as moderately low flying planes. i saw them for about 5 seconds until they disappeared back into the clouds.
