I would like to know with which alloy the ladder of the Apollo lunar module was manufactured and how was it fixed to the landing gear (welding, riveting collage)?According to the below photo, it looks like drawn tubes rolled and mandreled in the amount of the ladder and riveting on the edges of the bars). Am I good? Thank you in advance for your answers. |

Great photo of the case for the American Flag attached to the left side of the ladder. |

I remember reading somewhere the ladder was only rated for one astronaut at a time. In case one astronaut broke his leg during the moonwalk, the other astronaut could not stand on the top rung to pull his buddy up. |

I would be curious to know if the lunar module ladder was capable of supporting the weight of an astronaut wearing the full pressure suit and life support system backpack in 1g, if so, it should be capable of supporting the weight of two crew on the lunar surface.This may also depend on how/where each crewmember places their weight upon the ladder, as the ladder design was secured to the landing gear strut in three positions, with the remainder of the ladder not in contact with the strut. This Apollo 14 image shows the two crew standing on the ladder of the LM mockup. Note the weight distribution and positioning of the people. |

Unfortunately I don't think any conclusions about the strength of the LM can be derived from a 1g training mockup. |
