Witness Account

As I was at the West Jordan Costco pumping gas, I looked up at the sky. It was around 11 am. I noticed what I though was a group of white birds, assuming they were seagulls until I noticed just how high in the sky they were...with a plane flying under them.
As I was watching, I saw them act out of character for birds. They were white circles the more I observed them. They made patters that were linear, then circular, then a v, then linear and a circle again. I looked away for about seven seconds when the gas pumped stopped. When I looked back...the sky was completely clear and void I'd anything for miles. The orbs had completely disappeared.
Hours later, I remembered seeing one of the Army black helicopters flying low and slow not too far from there about 30 minutes before seeing the orbs. I remember the helicopter because they normally fly higher and faster, and I thought it strange. I don't know if the two events were related.
