I send my deepest sympathy to Lt. Commander Kevin J. Davis, who was the announcer of this Blue Angels air show.  He crashed his F/A-18 Hornet Number 5 during a Blue Angels performance on April 21, 2007.  We were very impressed of his spirit in the SF air show.  He also flew Number 6 for private demonstrations during the show.  There are many videos in the iTube of his demonstrations to reporters.
