Dutch scientists Olivier Hoes, Rolf Hut and Fedor Baart came to San Francisco to discover what happened to the three Alcatraz inmates who set out in a raft made of raincoats into the treacherous waters of San Francisco Bay on the night of June 11, 1962. Using state-of-the art, hydraulic software, coastal engineer Olivier Hoes created one of the most sophisticated flow models of San Francisco Bay ever built.
