Heh, I'll possibly put up a request for crew members - I always need names. Hmmm, this could work.
Last year, I put out a request for criminals in my writing group. A disturbingly large number of people wanted to be anti-space alien terrorists. I got one of 'em but good by having the medical examiner's officer offhandedly remark that the fact that the remains were identifiable at all was due to advanced chemical analysis, as the perp ended up as an interesting splash pattern on a wall.
