interesting video but a strange comment about the Trident II travel time from Nevada - nuclear sub in Lake Tahoe? 🤔
ReplyDeleteJust hook your Tuna Tin 2 up to it and - bingo!
ReplyDeleteThis massive antenna has even made it into the movies. In the film Divergent (and it's two sequels) it is featured prominently as a CGI-transformed protective fence that completely encircles the post apocaliptic city of Chicago. I was watching this movie with my son when I spotted it and got all excited and started yelling "hey that's the Russian Woodpecker antenna array WTF!". Of course nobody knew what I was talking about until I showed them pictures of it on the web!
