Two craft sighted in the night sky over Nashville, NC flying in a North Northeast direction.On Friday April 17, 2009 at approximately 22:36 hours a friend and I witnessed two objects in the sky over Nashville, NC. These objects flew side by side at a high rate of speed emitting no sound and leaving no vapor trail. They flew at a steady speed and at a constant distance apart from each other. There were no lights on these craft and seemed to be reflecting ambient light from the material they were made with. It resembled a semi polished aluminum or titanium. The craft flew in a North, Northeasterly direction.The speed at which the craft traveled was comparable to that of a low flying military fighter. The craft seemed to be approximately 20-25,000 feet in the air. I am no flight expert but it seemed to be at an altitude slightly higher than what a helicopter would fly.The craft appeared to be flying in a formation with one slightly ahead of the other.As stated before, these craft traveled without making a sound. I only noticed the objects because I had went outside to smoke and happened to be looking at the stars noticing what a clear night it was. The objects seemed to be round or a slight elliptical shape.This is the second time I have witnessed unidentified objects. The other sighting was approximately 17 years ago near Warrenton, VA. That sighting was confirmed by documentation with a government agency of other reports.
