I live in the St. Louis suburb of Kirkwood, Missouri. Sunday evening March 15, 2015 at about 8 p.m. my wife and I were standing in our front yard looking east watching our kids play and enjoying the warm weather when we saw a strange sight in the eastern horizon. At first we saw what we thought was a plane or helicopter with weird almost pinkish lights that was not blinking like you normally see. It was flying slower than I would expect a jet to fly although we sometimes see them flying slowly getting ready to land at Lambert Airport. Then several more came into view following the first one. They seemed to be flying more or less in a line all heading the same direction, from south to north, at the same speed across our field of vision. We could see them through the trees because the trees do not have leaves yet. My wife counted a total of 8. Then before they left our field of vision they all abruptly disappeared at the same time. Just went dark. They were too far away from me to make out a shape, but my wife thought they were disc like. It only lasted a couple of minutes and I did not have my phone so I did not get any pictures or videos.
