A sailor undergoes the traditional 'Crossing the Line' initiation aboard the aircraft carrier USS Franklin D. Roosevelt (CVB-42), crawling across the deck as part of the U.S. Navy's time-honored ceremony welcoming first-time equator crossers -- 'Pollywogs' -- into the fraternity of 'Shellbacks.' The handwritten caption, 'Don't be P.O.'d, it's all in fun,' reflects the good-natured spirit behind this enduring naval tradition. Project: 218371
