Editing Apollo 5 (section)

==Delays==
As with [[Apollo 4]], there were significant delays for Apollo&nbsp;5. The primary cause of the Apollo&nbsp;5 delays was the LM, which was behind schedule. Apollo Program Manager [[Major general (United States)|Major General]] [[Samuel C. Phillips]] had originally hoped that the uncrewed test flight of LM-1, the first lunar module, would launch in April 1967. Anticipating six months for checkout and testing of the vehicle, NASA asked Grumman to have LM-1 delivered to [[Kennedy Space Center]] in Florida by September 1966, but due to difficulties in manufacturing LM-1, delivery was repeatedly delayed. The delivery date was still uncertain when AS-206, the [[Saturn IB]] launch vehicle planned to boost LM-1 to orbit, was erected at [[Cape Canaveral Space Launch Complex 37|Launch Complex 37]] in January 1967. After the fire that month that killed the [[Apollo 1]] crew, the launch vehicle planned for Apollo&nbsp;1, AS-204, was moved from [[Launch Complex 34]] to Launch Complex&nbsp;37 and replaced AS-206.{{sfn|Benson|Faherty|1978|p=435}} This was done because AS-204 was the last Saturn IB with full research and development instrumentation, and, with crewed flight on hold, NASA wanted to use that booster for the first flight of the LM.{{sfn|Astronautics 1967|p=81}}{{efn|Launch vehicle AS-206 was subsequently designated for a potential second uncrewed flight of the LM, and when this proved unnecessary, was placed in long-term storage. It was renovated for crewed flight and flew in 1973 as the launch vehicle for [[Skylab 2]], taking the first crew to [[Skylab|that space station]].<ref>{{cite web|last=LaPage|first=Andrew|work=Drew ex Machina|title=SA-206: The Odyssey of a Saturn IB|url=https://www.drewexmachina.com/2018/05/25/sa-206-the-odyssey-of-a-saturn-ib/|date=May 25, 2018|access-date=September 12, 2021}}</ref>}}

With no LM yet available, Grumman built a plywood mockup of one at Launch Complex&nbsp;37 to aid in facilities verification.{{sfn|Orloff & Harland 2006|p=139}} On May&nbsp;12, 1967, Apollo Program Spacecraft Manager [[George M. Low]] informed NASA headquarters that Grumman was committed to a June&nbsp;28 delivery of LM-1, though Low noted that the goal would be hard to meet.{{sfn|Ertel et al|p=132}} On June&nbsp;23, LM-1 arrived at Cape Kennedy on board [[Aero Spacelines]]' [[Aero Spacelines Super Guppy|Super Guppy]]; the stages were mated to each other four days later.{{sfn|Orloff & Harland 2006|p=139}}{{sfn|Brooks 1979|p=241}} A 400-person team under John J. Williams, a veteran of launch operations for both [[Mercury program|Mercury]] and [[Gemini program|Gemini]], checked to see that LM-1 met specifications, after which they supervised Grumman technicians, who tested and modified the vehicle.{{sfn|Brooks 1979|p=241}} Due to leaks in the LM's ascent stage, the two stages were demated in August, and after these were fixed and the stages remated, another leak developed and the stages were demated again in September. During this time, several pieces of equipment were removed for repair by Grumman; the stages were remated again in October.{{sfn|Orloff & Harland 2006|p=139}}

As of September&nbsp;6, 1967, Apollo&nbsp;5 was running about 39&nbsp;days behind the plan established on July&nbsp;18, but all known issues were being dealt with, with the exception of some leaks from the propulsion system.{{sfn|Ertel et al|pp=153–154}} Most mission documents were ready by late 1967; Mission Director [[William C. Schneider]] issued mission rules on November&nbsp;18, 1967. The following day, LM-1 was mated to its launch vehicle, and the space vehicle readiness test was completed in December. In early January 1968, the office of NASA Administrator [[James E. Webb]] announced that Apollo 5 would be launched no earlier than January&nbsp;18, 1968. Minor faults such as clogged filters led to some additional delays. The countdown demonstration test concluded on January&nbsp;19 and an abbreviated 22-hour countdown began on January&nbsp;21.{{sfn|Brooks 1979|p=242}}{{sfn|Orloff & Harland 2006|p=140}}
