we were camping in a friends yard fairly dark night as I recall . we saw 5 disk shapes flying in a v- formation the had a greenish white glow and flew off toward the east. about 20 seconds later a single disk flew past heading in the same direction. I have no idea if this has any bearing to what they were but at the time we had an airforce base only a few miles away that was closing as part of the cut backs in the 70's
