Don Elkins and Carla L. Rueckert gave an interview to an Atlanta TV station program in 1978 which has not been viewed by any outside of those who have visited L/L Research.
Thanks to Renee, this interview is now available in five parts on L/L's YouTube channel. Total length 1 hour 11 minutes.
The recording has been sitting on a VHS in house for years. Recently it was switched over to DVD by a local company in Louisville. Unfortunately they did not edit the video to improve the quality. They just performed a direct transfer from VHS to DVD. Consequently the quality is poor, but the content remains, in this author's opinion, fascinating.
