Transcript for Feed Frenzy: Nyad's Seven-Hour Mystery
In tonight's feed frenzy, the world celebrated when diana nyad stumbled on to the shore. It was a record breaking 103 mile triumph for someone of any age. Much less a 64-year-old. The first to make it without a shark cage. But now some are alleging that her team's account of the swim doesn't add up. Now she is out to convince skeptics she broke the record fair and square. Why is team nyad failed to provide a more detailed account of her 53 hours in the ocean? This swim was not documented independently by impartial observers. And why wasn't it recorded with continuous video. And two, could she have really gone without food and water for a crucial 7.5 hours? No refuelling for that long? And finally her speed. Nyad is know for her plodding pace and in this case slow and steady seems to have won the race. But she more than doubled her average speed in the second day in the water from 1.6 miles an hour to about 4 miles an hour. She started and ended the journey at the same pace but the surge in the middle has people asking if she clung to a boat. Without conclusive evidence, it's hard to know.
