April 1969 issue of Skin Diver Mag. I came across an article for a Underwater Sightseeing Bus.. Yep. You read that right.. An Underwater Sightseeing bus. Apparently this idea didn't get very far off the ground. (Ha! See what I did there!) The first model was to use a 50 tonne, twin keeled submarine. It was capable of carrying up to 8 people and would be available to film crews or scientists. A 2nd version of the bus was to be 63 feet long and carry 40 passengers. I can't even begin to fathom (Hehe there's another pun for ya!) all the variables that would make this such an improbable mode of sightseeing. I mean, even Disney's famous submarine ride has many issues and it's on a track and in a secured, controlled environment. I guess it was never meant to be. The owners, a company called 'Indies' just couldn't keep their head above water.. (I'll see myself out.!)
