Michelle Obama gets off a helicopter

First Lady Michelle Obama (rear, on stairs) exits the helicopter known as Marine One, preceded by President Barack Obama and their daughters Sasha (left) and Malia Obama. (Marine One is the designation of any U.S. Marine Corps helicopter that carries the U.S. president, hence the Marine saluting at left. Marine One often ferries the president from an airport to the White House.) The date was August 29, 2010, and the Obamas were returning from a family vacation.
