Did Al Worden wear Dave Scott's helmet visor with the red stripe during his transearth EVA? I found conflicting reports and I could not see it in the video. Can anyone confirm this? |

The Apollo 15 Flight Summary in The Apollo 15 Flight Journal mentions that Worden used Scott's lunar surface visor assembly during the transearth EVA. |

I asked Gene Cernan a couple of years ago a about the helmet and PLSS backpacks. He advised me that the oxygen purge system (OPS) and the commander's visor and sunshield were saved and were used by the CM pilot during the spacewalk to retrieve the film canisters. The OPS had an oxygen supply and a regulator system. I never thought to ask if the second OPS was saved also for he LM stand up EVA at the same time. But photos of Apollo 17's discarded PLSS packs show there was no OPS attached. I think it was the same for all the J missions. The commanders sunshade/visor was saved with the OPS system. I think the OPS was discarded after the spacewalk. |

- Worden wore Scott's LEVA and OPS on the Apollo 15 transearth EVA.
- Mattingly wore Young's LEVA and Duke's OPS on the Apollo 16 transearth EVA.
- Evans wore Cernan's LEVA and OPS on the Apollo 17 transearth EVA.
I don't think the LMP, who was positioned at the open hatch, wore an OPS on the transearth EVAs. After the moonwalks, both OPS were saved in case there was a CM-LM docking problem in lunar orbit that would require the CDR and LMP to perform an EVA to get back into the Command Module. |

Why for the Apollo J mission transearth EVAs was the command module pilot not equipped with the same A7L-B suit like the commander and lunar module pilot?During the Skylab missions, all the crew had the same A7L-B suits. Editor's note: Threads merged. |

Everything was done on a 'what was needed for the next flight mentality'. It was just easier to change the procedure than to change the equipment.Don't forget a lot of people wanted to end the lunar exploration after Apollo 14. |
