The mission's sequence number originally had been STS-13, and it has been rumoured that the entire change in the numbering system for Space Shuttle missions after STS-9 was done to avoid having to fly "STS-13". NASA still remembered Apollo-13!! The crew, Robert Crippen, Francis "Dick" Scobee, George "Pinky" Nelson, Terry J. Hart and James van Hoften decided to challenge fate and Scobee designed a patch showing symbols of bad luck, such as a black cat, the number 13 and a Shuttle flying from underneath(!!) the cat to space. The patch has the crews nicknames, CRIP, DICK, TJ, OX and PINKY on it. Apparently, the patch was extremely exclusive, George Nelson has stated that he understood that less than twenty of these patches have been manufactured.
