as of 21 january 1960, the little joe series of five actual and attempted flights had expended four of the six test boosters north american had made for nasa and five prototype capsules made in the langley shops. the primary test objectives for these solid-fuel-boosted models were an integral part of the development flight program conducted within nasa by the space task group, with langley and wallops support. now only two little joe boosters remained for the qualification flight tests. north american had manufactured seven little joe airframes, but one of these had been retained at the plant in downey, california, for static loading tests. stg ordered the refurbishment of this seventh airframe so as to have three little joe boosters for the qualification flight program. the success of little joe 1b in january 1960 meant that the next flight, the sixth, to be known as little joe 5, would be the first to fly a real mercury capsule from the mcdonnell production line. in passing from development flight tests with boilerplate models to qualification flight tests with the "real mcdonnell" capsule, the space task group moved further away from research into the development and toward operations.
