Formation of four lights traveling at an apparent fast rate of speed silently across the night sky.From Fresno California, on August 24 th, 2012, I woke up needing some water and I decided to go outside and check the clear star lit sky, I was hoping to see some falling stars but instead I saw a UFO (or four of them)! It was almost straight up in the early morning sky (2:30 AM) a bit to the South sky, I saw a fast moving line four lights (about equal to the stars that were out) traveling from West to the East, from one side of the sky to the other ending in their disappearing behind the tree line. They were spaced far apart but clearly together. The line was side by side not in a follow the leader row, the line was perfectly straight, each light was constant, not blinking and without color of any kind, the speed was difficult to tell now knowing the distance but it was very fast and took about 4 seconds to go all across the sky. There was sound at all.This is the first time I have seen such an event, I feel lucky to have seen it, but at a loss to identify it as something earthly. I am 62 years old, and have observed many different type planes, having been raised near Castle Air Force Base and near both commercial and military air bases. I would love to learn if there has been any similar sightings! This report is not a hoax.
