In 1958 Clark C. McClelland was assigned to the national space program at Cape Canaveral, Florida, and helped launch or viewed 673 rockets and spacecraft. In addition to being an Aerospace Engineer and Technical Assistant to the Apollo Program Manager during the Apollo moon landings, McClelland and other SpaceCraft Operators did extensive technical checkout of simulated flights and mission objectives of the various shuttles to assure orbital success and the personal safety of the astronauts. Clark McClelland knew many of the astronauts who perished during the Challenger disaster and certainly did all he could to keep each shuttle from such a repeat accident.
He has held important positions involving such manned projects as Mercury, Gemini, and Apollo lunar landings, Skylab, the Space Shuttle and the Space Station. He was assigned to the cockpit of the Space Shuttle missions as a SpaceCraft Operator (Ground Test Astronaut).
McClelland’s name is on three commemorative monuments of the Mercury, Gemini, and Apollo missions – His name will also be on the Space Shuttle, International Space Station and the Deep Space Missions monuments in the future.
