Each month, National Geographic magazine features breathtaking photographs in Visions of Earth. Among the photos selected this month is this one of Mahó Beach in St. Maarten. The photo, by Fabi Fliervoet, shows a Boeing 747 on approach to Princess Juliana International Airport. Mahó beach, the narrow stretch of white sand on the Caribbean island’s Dutch side—the rest is French—is a world-famous plane-watching spot. One of my teenage son’s favorite spots—he’s an an avid plane spotter and aviation photographer.
