This craft hovered over the tn river for a very long time. i was a young boy approx 7-8. i remember my mom and dad and all our neighbors watching this. i'll never forget how calm, quiet and peaceful everything felt. it was a huge bright green object, with landing legs viable. best way i can describe it is like the lunar lander but approx 5 times the size. i have tried for years to find any info on this, but have not been able to. i'm a retired police officer now, and would just like any info on this available. i'm willing to speak with your investigators to help any way i can.
