Editing Apollo 1 (section)

=== New mission naming scheme ===
The astronauts' widows asked that ''Apollo 1'' be reserved for the flight their husbands never made, and on April 24, 1967, Mueller, as Associate Administrator for Manned Space Flight, announced this change officially: AS-204 would be recorded as Apollo{{nbsp}}1, "first manned Apollo Saturn flight – failed on ground test".<ref name="MarAprChron">{{Cite book |last1=Ertel |first1=Ivan D. |url=http://www.hq.nasa.gov/office/pao/History/SP-4009/contents.htm#Volume%20IV |title=The Apollo Spacecraft: A Chronology |last2=Newkirk |first2=Roland W. |last3=Brooks |first3=Courtney G. |publisher=[[NASA]] |year=1969–1978 |volume=IV |location=Washington, D.C. |chapter=Part 1 (H): Preparation for Flight, the Accident, and Investigation: March 25 – April 24, 1967 |lccn=69060008 |oclc=23818 |id=NASA SP-4009 |display-authors=2 |access-date=March 3, 2011 |chapter-url=http://www.hq.nasa.gov/office/pao/History/SP-4009/v4p1h.htm |archive-date=February 5, 2008 |archive-url=https://web.archive.org/web/20080205020128/http://www.hq.nasa.gov/office/pao/History/SP-4009/contents.htm#Volume%20IV |url-status=dead }}</ref> Even though three uncrewed Apollo missions ([[AS-201]], [[AS-202]], and [[AS-203]]) had previously occurred, only AS-201 and AS-202 carried spacecraft.

The crewed flight hiatus allowed work to catch up on the Saturn V and lunar module, which were encountering their own delays. Apollo{{nbsp}}4 flew in November 1967. Apollo{{nbsp}}1's (AS-204) Saturn IB rocket was taken down from Launch Complex 34, later reassembled at [[Cape Canaveral Space Launch Complex 37|Launch complex 37B]] and used to launch [[Apollo 5|Apollo{{nbsp}}5]], an uncrewed Earth orbital test flight of the first lunar module, LM-1, in January 1968.<ref>{{Cite web |year=2001 |title=Apollo Program |url=http://www.nasm.si.edu/research/arch/findaids/bellcomm/bci_sec_21.html |access-date=January 26, 2013 |website=[[National Air and Space Museum]] |series=Bellcomm, Inc Technical Library Collection |publisher=[[Smithsonian Institution]] |location=Washington, D.C. |page=Subseries III.D.3 |no-pp=y |id=Accession No. XXXX-0093 |archive-date=April 29, 2012 |archive-url=https://web.archive.org/web/20120429235023/http://www.nasm.si.edu/research/arch/findaids/bellcomm/bci_sec_21.html }}</ref> A second uncrewed Saturn V AS-502 flew as [[Apollo 6|Apollo{{nbsp}}6]] in April 1968, and Grissom's backup crew of [[Wally Schirra]], [[Donn F.
