Multiple round, bright orange objects flew above High Point, NCObjects seen were round and were bright orange. They did not leave any afterglo as they silently slid across the sky. All of the objects seen traveled in the same direction heading north. They traveled in the same straight path and elevation. During the time we observed them, the sky was clear of cloud cover and we did see other planes flying at higher elevations in relation to the objects.Initially, we saw two such objects. Within minutes after them, we observed a formation of seven. During the time when we saw the larger formation, we tried to place calls using our cell phones, but our phones seem to be temporarily "dead". We do not know if this is a coincidence or connection to the events.After the initial large group flew by, we watched as they traveled mostly in pairs.Several of the objects looked like they were trying to catch up with the preceeding group, as they were flying at a higher speed.We have multiple videos taken with digital cameras.
