One of the great things about living in my neighborhood is the annual performance of the Air Force Aerial Demonstration team, better known as the Thunderbirds, supporting the graduation ceremony at the United States Air Force Academy. It's always a magical moment, the cadets throw their dress caps in the air and the Thunderbirds scream overhead.
Unfortunately in this era of Sequestration, that wasn't possible. The Thunderbirds had to cancel their demonstration schedule and are essentially grounded. Not willing to let tradition of a flyover die, a group of aviators and their World War II era Warbirds took up the mantle and volunteered to do the flyby.
I managed to see them from a distance, so my own photos aren't too great. If you ever get a chance to see a Service Academy Graduation, take it, it's a really great event to see.
