Warbird formation flights are my favorite part of an airshow.  Whether it's a warbird flying with a modern aircraft (called Heritage Flights by the Air Force and a Legacy Flights by the Navy) or multiple warbirds, these flights are a great opportunity to see the aircraft that have helped defend our nation.
