Linear formation of about 30 individual lights traveling SW to NE

My wife and son called me out side because there was a strange line of moving lights that seemed to be atleast 2 football fields long. They were higher then an airplane and there were around 30 individual objects (lights) traveling at different speeds within the linear formation as some seemed to slow down and speed up to not hit another light . The lights were almost the same color as stars but had a blue tint. They traveled across the sky for atleast a minute while we were calling out across the street to neighbors and another gentleman to verify they too could see it. The lights appeared to be traveling upwards and then almost all at once disappeared. I tried to listen to see if I could hear sounds but I could not. The sky was clear of any clouds my view was not obstructed at any time. I immediately came in to look up where to report it.
