Author and historian Tom McMillan talks about the huge flag that flew over Fort McHenry in the War of 1812 with the British. It was the flag that Francis Scott Key saw through the night that inspired the national anthem, "Star Spangled Banner." McMillan researched the family that took the flag home and kept it safe for 90 years before donating it to the Smithsonian. The little twists and turns of history are uncovered and explained by McMillan who talks to host Jim Fausone.
