The launch of AS-501 was originally planned for late 1966, but was pushed back by stage development problems to April 1967.
The first piece to arrive at the Kennedy Space Center was the S-IVB third stage, built by the Douglas Aircraft Company.
Small enough to be transported by a specially built plane, the "Pregnant Guppy" built by Aero Spacelines, Inc., it arrived on August 14, 1966.

The other stages were much larger and had to travel by barge along the Banana River.
The S-IC first stage, built by the Boeing Company, arrived next on September 12 from Michoud, Louisiana.
