Driving up through route 8, saw two aircraft just sort of hovering in the air.

I am an experienced pilot and flight instructor, so seeing things in the sky is normal to me. What isn’t normal is how these two aircraft moved and hovered. Driving up Route 8 North through the S-turns before Naugatuck, I saw two white circular objects in the sky. They just stayed stationary for about 5-8 minutes before slowly beginning to move Westbound. They maintained equal distance apart and went the same speed when moving. The shape, white color illuminated by the rising sun, hovering and movements just seemed off and unlike standard aircraft.
