The helicopter carrying Pope Francis, sitting next to left window, flies on its way to Castel Gandolfo Saturday, March 23, 2013. Crowds are beginning to gather in the central square of Castel Gandolfo to catch a glimpse of history: Two popes meeting for lunch and presumably discussing the future of the Catholic Church. Pope Francis flies by helicopter Saturday to the papal residence in the Alban Hills south of Rome where Pope emeritus Benedict XVI has been living since resigning Feb. 28, the first pope to step down in 600 years.
