Today, yachts and executive jets are accoutrements of great wealth. Microsoft founder Paul Allen’ luxurious 416-foot “Octopus? is one of the world’s largest yachts, and his Boeing 757 is a mega executive jet. Billionaire Sheldon Adleson has three jets, a Boeing 767, 747 and 737. More than a century ago, yachts and Pullman palace cars were the generic trappings of affluence. William K. Vanderbilt and his family steamed along the Eastern seaboard in his 285-foot yacht Alva and traveled the rails in two plush Pullman cars. C.P. Huntington also had two Pullmans, Oneonta No. 1 and No. 2, the former with a kitchen, stateroom, dining room, and quarters for servants, the latter divided into staterooms, a drawing room and an observation compartment.
