Last evening at work, through dark windows in a rural area, I saw low-flying red lights (one after another, 3 or 4). Considering how low they were flying, they were going very fast. If they were planes, I saw no headlights and they flew too fast. In the moment it took to realize their speed was too fast for their height, they all were gone. They were going horizontally, not down. Going south.
There is an old bridge a little ways east of where they flew. They must have known it, but without headlights, geez, it would be risk not hitting the top of the bridge. Because they didn't look much higher than that. But, they must have known it was away to the east a little.
