Diana won't be the first to swim the distance, but she will be the first to do it without using a shark cage. She's already accomplished similar feats by swimming from the Bahamas to Florida and circum-swimming Manhattan (gross), but Cuba comes with a political message for greater cooperation between the two countries.
Our favorite part of her journey? The massive support squad: "She will be accompanied by five yachts and four kayaks, and will be backed by a 45-person support team, including trained shark divers and electronic devices designed to repel the predators." Our greatest question isn't if she'll make it or how long it'll take, but how does the paperwork get processed? And can the coast guard stop the group and send them back? Guess we'll find out in a couple days when Diana concludes her swim in the Keys.
