 The Apollo 8 spacecraft was placed on top of the rocket on September 21 and the rocket made the slow 3-mile (5 km) journey to the launch pad on October 9. Testing continued all through December until the day before launch, including various levels of readiness testing from December 5 through 11. Final testing of modifications to address the problems of pogo oscillation, ruptured fuel lines, and bad igniter lines took place on December 18, a mere three days before the scheduled launch.
