Large dark craft on I 59 in MississippiI was on I59 N in big truck 70 mph at about the 115 mile post marker, Large dark craft heading south above or beside I59 S Bound at a slow pace, Band of light around outer edge 3 circles of light under, all lights pulse from on to dim and back on slowly. Light was not real bright and did not hurt your eyes when looking at them. Not like any other craft I ever saw.
