I work 00:00 to 07:30, and have breaks at 02:00,04:00 and 06:00.On Friday morning at 06:00, I was outside on break. It was a clear morning and the sun wasn't coming up yet. I was looking at the sky enjoying a clear morning when I saw a starlike object moving at faster than ordinary aircraft but not outstandingly fast. The object was moving from the south-east to the north-west,NOT on path to any local airports. I plotted where Gtr.Pittsburgh Int'l Airport and Allegheny County Airports where,and this object deffinitely was neither heading for or coming from either. Local air traffic typically heads north-east to south west for either airport and is ussually low enough to discern typical nav.lights and you can hear the engines. This same type of object was seen at the same location mid August heading directly south to north for 4 nights.On 2 back to back nights 2 objects were seen together.On the first sighting 2 were in a loose formation flying side by side with the "wingman" casually passing "lead" as they passed overhead. The second sighting they stayed together,3rd and 4th night there was a single object. Around October,another sighting of the same type of object was seen,this time traveling north to south. On one occassion,The object was heading south,then made a course change of about 45deg.toward the south-east from one star to another and continued straight south. The times of the August sightings was between 02:05 and 02:10 and in October,between 04:15 and 04:25. During the August sightings,myself and other co-workings were just enjoying the clear nights and watching for shooting stars,and learning the constellations.We were looking at one constellation when I asked "hey are those stars moving?" That's when the first 2 passed overhead with the one passing the other. Then we were joking that they were chinese satellites checking up on us. My first impression was that they were satellites, but never heard of 2 side by side like that,Then I thought they were high flyers,but Gtr Pitt was to the south west and they typically wouldn't fly over us in this manner. The location of the sightings is 40.41823/79.75649
