In the 2006 incident, trainer Ken Peters was pulled under water during a performance of the "Believe" Shamu show when the whale, Kasatka, grabbed his foot and would not release it. Approximately 8 minutes elapse from the time Kasatka grabs K. P.’s foot until she lets him go. A lot of that time is spent underwater. When Kasatka allows K. P. to surface, K. P. is noticeably shaken but he remains remarkably poised and free of panic. He calmly pats Kasatka as he gulps for air. Kasatka pulls him underwater several times, once taking him to the bottom of the pool, where they linger for a very long time. When Kasatka finally allows K. P. to go free, he swims rapidly to the side of the pool. As he does so, Kasatka turns and swims after him. Another trainer helps to pull K. P. away from the side of the pool and the advancing Kasatka.
