The news said today that the unfortunate lady was riding in the front of a boat going 25 MPH when the Eagle Ray jumped out of the water and landed right on her. It also said that rays will do this when they are trying to escape predators, give birth, or remove parasites. It was poor timing, for both.
My family did the Stingray City Tour when we were in the Grand Cayman last summer without incident. We all even got to hold one of them who was named, "Jennifer" and she was so gentle, even seemed to like being petted. They told us to avoid putting our hands near her mouth or risk getting a "serious hickey"....lol. Like msblackjack said, be sure to do the stingray shuffle to avoid stepping on them. Also, no fins are allowed while you are mingling with them, for your safety, as well as theirs.
