Grandview, MO - Formation

The first object it was very dim and hard to see until it lit up for a second and dimmed back down repeatedly for every five seconds.

Seven objects were seen that night. The first object flew by at five mph, it was very dim and hard to see until it lit up for a second and dimmed back down for every five seconds. After that one passed, another showed up a few miles away from the first one. It was very bright and it also seemed to hover at five mph. The third appeared and it was opposite the direction the second object was. As I watched, I counted 7 bright objects. The objects were in a double line formation, atleast the six were, with the first leading the group. Each line consisted of three objects. If you were to look at the line in pairs of two, the objects formed a short, diagonal line. The colors of the objects were a sort of bright white(the last six) and they all seemed to be a circle or a oval.
