one hour. drill sergeant. on your first stroke, here we go. chief handler. bonnie is a rock. she s a take-charge, no-nonsense, say it in a few words. she knows me as an athlete. bonnie will lead an army of handlers that will follow diana s every stroke to nourish, encourage and protect her. one of their biggest concerns sharks. these are great waters for sharks. luke tipple is the team s shark diver. he knows how dangerous these waters can be. in this water we d look for white tips, hammerheads, caribbean reef sharks. this animal has evolved to dominate the ocean. they have a sixth sense. they can feel the electricity in the water. they know that we re there. that s why in 1978 diana swam in a shark cage. today she just uses this. sharks are tremendously sensitive to this. this is actually in the kayak. it s called a shark shield. and off the coast of the
