(CNN)Two jets from the military's premier flight demonstration squadrons, the Blue Angels and Thunderbirds, crashed Thursday. The pilot of a Blue Angels jet was killed while practicing for a weekend air show only hours after a Thunderbird F-16 crashed following a flyover at the U.S. Air Force Academy commencement ceremony attended by President Barack Obama. The Thunderbirds pilot safely ejected before the plane went down in Colorado.
