Watching the 18 ft. Great White Sharks swimming along the beaches of Cape Cod on tv recently makes me less excited about going for a dip next summer. I would feel greatly relieved to see a balloon, aerostat hovering a few hundred feet off the beach knowing someone was monitoring the shadows of creatures that can make a snack of me. I can swim but no one has explained to me how to free myself from Jaws. I like to eat seafood not be seafood.
They were near Orleans and Chatham I believe but that's just where the small planes were filming. They are everywhere from Argentina to Nova Scotia. Maybe even a few in Australia and South Africa.
