WIKIPEDIA EXCERPT
Stanley David Griggs was a United States Navy officer and a NASA astronaut. He is credited with conducting the first unscheduled extra-vehicular activity of the space program during Space Shuttle mission STS-51-D. Griggs was killed when the vintage World War II-era training aircraft he was piloting – a North American AT-6D – crashed near Earle, Arkansas.
