This is Philippe Croizon, 42, a quadruple amputee who swam the English Channel this weekend. Using prosthetic legs outfitted with flippers, he made the swim in 13.5 hours, almost half the time he expected to take. From the AP:
Croizon's specially designed leg protheses, which end in flippers, allow him to propel himself through the water. His truncated upper arms go through the motions of the crawl, and he breathes through a snorkel."Quadruple amputee swims across English Channel"
The swimmer lost his arms and legs after suffering an electric shock in 1994 as he stood on a ladder adjusting his television antenna, which touched a power line.
