The eldest son of Ottavio Missoni, founder of the eponymous Italian fashion brand, disappeared when a small tourist biplane fell off the radar off the coast of Venezuela Friday. The plane, which carried six people, was 10 nautical miles from its takeoff point in Los Roques when it disappeared. The disappearance immediately spurred a search-and-rescue mission by the Venezuelan government. The incident bears creepy similarities to another disappearance five years ago, when a plane of Italians disappeared in the same area on January 4. Missoni, who was spending the holidays at a Venezuelan resort, is the brand's marketing director.
