NOTES
1. Flights SA-1 through SA-4 were Block I and SA-5 through SA-10 were Block II.
2. Vehicles SA-1 through SA-4 had dummy upper S-IV stage. SA-5 through SA-10 had live S-IV stage.
3. SA-1 through SA-5 had Jupiter nosecone payload. SA-6 through SA-10 carried boilerplate spacecraft. SA-8 through SA-10 also carried Pegasus satellite.
4. SA-9 flew prior to SA-8 due to fabrication completion dates.

NOTES
1. AS-201 was erected with S-IVB-500F and S-IU-200F/500F on 18 Aug. 1965 as facility check of pad 34.
2. AS-203 only carried a nosecone as a payload.
3. AS-204 was previously scheduled for first manned flight, Apollo 1. After the Apollo 1 fire the vehicle was de-erected from pad 34 during March 1967.
4. AS-206 was previously stacked on pad 37B, January 1967, for first LM flight. After Apollo 1 fire was de-erected, March 1967, and sent to MAF for storage.
5. AS-206 had rollout to pad 39B, 9 January 1973, with FVV spacecraft as facility check for milkstool configuration. It returned to VAB on 5 February 1973.
6. Instrument unit S-IU-207 flew on flight AS-208 and vice a versa.
7. AS-209 was used as standby rescue vehicle during Skylab and ASTP. It remained on pad 39B until the return of Skylab 4.

NOTES
1. AS-500F returned to VAB on 8 June 1966 because of Hurricane Alma threat. After two days it was back on pad 39A where it remained until mid-Oct 1966.
2. AS-501 was stacked using S-II spacer due to late delivery of S-II-1. 501 was destacked twice - once for spacer and once for S-II checks.
3. AS-502 initial stacking used spacer due to late S-II-2 arrival.
4. AS-503 was de-stacked after initial stacking to allow S-II to go back to MSFC for man-rating checks.
5. AS-510 was moved from high bay 1 to high bay 3 prior to stacking of spacecraft.
6. AS-511 was initially rolled out on 13 December 1971 and was returned to VAB on 27 January 1972 to allow for RCS fuel leaks in SM to be fixed.
7. The S-IVB entries for Skylab 1 refer to the OWS and the spacecraft entry refers to the ATM, MDA etc.
