What's black and white and flies all over? Shamu One, the killer whaleplane, which, beneath a $125,000 paint job, is actually a new Boeing 737-300. Dallas- based Southwest Airlines, in an effort to draw attention to its role as the official carrier of San Antonio's Sea World, decorated the jet to look like one of the theme park's famous cetaceans. After a promotional tour, Shamu One begins regular service for Southwest this week. For passengers, no doubt, it offers a much more comfortable ride inside a whale than Jonah had.
