I saw this on the news last night. Wasn't in Florida. It was down in San Antonio, Texas, at Sea World. We've a couple of orcas down there they call Shamu. He just went nuts, but from what I could tell from the footage, he wasn't really attacking his trainer because he never once opened his mouth to bit him. He just was swimming round and round and top of him. Knocking him under and such. Didn't really seem hurtful to me, just an orca getting way to excited and playing roughly. Trust the news to fluff things up like it was a true orca attack...
