Preparation of the spacecraft in the industrial area at Cape Kennedy, which began with the receiving inspection and ended when the spacecraft was transferred to complex 19, was generally limited to non-test activity with certain exceptions.

These were the special requirements of the communications test of spacecraft No. 3 and the propulsion verification tests of spacecraft Nos. 2 and 3. Industrial area activity included cleaning up miscellaneous manufacturing shortages, updating spacecraft configuration, installing pyrotechnics and flight seats, building up the rendezvous and recovery section, and preparing the spacecraft for movement to the launch complex. These preparations for spacecraft No. 3 were completed February 4.
