I can see what is in front of my face. Have you ever watched some one you love go scuba diving?
You get a good eye for seeing them pop up.
This was a scuba diver and Fuddy saw it, too. She probably thought they were there to help.
I know enough about diving to know that a diver wouldn’t slip out of his tank or re-breather if he was tasked ... look at #7 and compare it to #19. If the yellow is a tank or re-breather, the ‘diver’ is no long attached from one frame to the other. The yellow is the sole of someone’s shoe. I took my frst dive at 19, in a swimming pool. The next attempt was off Zuma Beach. I lost some equipment trying to get through the breakers. I’m 68. I know enough to know there is no diver shown in those images.
