Lights in the skyI looked up at the night sky and noticed between 30 to 40 rectangular objects moving west to east. They appeared to be very far away. I noticed there were four colours present, red, green, yellow and blue. These coulours were in random order. The objects appeared in three rows. Under the third row was one single yellow rectangular light, larger and longer than the rest. This light appeared to be trying to catch up to the front of the leading crafts and slowed as it approached the front of the formation. After approx 30 seconds all of the lights dimmed into nothing.((NUFORC Note: Witness indicates that the date of the incident is approximate. PD))
