Portrait of Virgil 'Gus' Grisom, Edward White and Roger Chaffee wearing NASA space overalls with a model of the Command Module. All three were killed when fire, caused by an electrical spark and fanned by the pure oxygen atmosphere, swept through the cabin of the Command Module during a routine Earth-based test on 27th January 1967. The mision, which would have been the first piloted flight of the Saturn/Apollo spacecraft, was designated as Apollo 1 in honour of the crew. Grisom became America's second man in space when he flew on Mercury-Redstone 4 in 1961.
