Having been on many cruises I can assure everyone that you can tell when a window is open. Mr. Anello claims he's color blind and that may be why he couldn't tell the window was open even though the windows have a fairly dark tint to them. However, even if that is true you can hear sound and feel air through them. The open part of the window is pretty high. The bottom part of the window doesn't open. The grandfather actually rested on the railing for eight full seconds before picking his grand daughter up and lifting into the rail. He holds her for 34 seconds, let's go of her with one arm and then she slips from his grasp. It's a horribly tragic accident but nevertheless it's his fault. He cannot admit this to his family but it's highly unlikely he didn't know the window was open. A blind person would hear sound and feel the warm air.
