It's not clear whether Travel + Leisure magazine overlooked the ongoing ugly-or-art debate [2] over the big, blue Mustang sculpture before concluding that Denver International Airport is among the most beautiful airports in the world. "The product of a hasty sketch by Denver-based architect Curtis Fentress, who had three short weeks to cook up a design concept, the airport features a Teflon-coated tensile fabric roof---the world's largest when the airport opened in 1995---and looks like a village of giant white tepees," the magazine writes [3]. The publication names only one other U.S. airport---JFK in New York City. A few others on the list include Terminal 3, Beijing International Airport, China; Terminal 4, Barajas Airport, Madrid, Spain; and Kansai International Airport, Osaka, Japan.
