I just watched an interesting account from Stan Lebar of a piece of metal from the Launch Umbilical Tower (LUT) on Apollo 13 that could have damaged the rocket during launch and was wondering if that was an isolated case or where there other times during the Saturn V launches that that happened? Did they even find out how that piece got loose? |

I am sure it wasn't an isolated instance. Shuttle had recurring issues of the same type. |

How can you be sure it wasn't an isolated incident? Also I'd like to keep this thread focused on damage to the Saturn V. The shuttle is a whole different thing when it comes to damage. |

The shuttle-era fixed service structure was built from the same launch umbilical tower used during Apollo. So it stands to reason that if the FSS suffered damage from the shuttle's thrust and exhaust, then the LUT suffered the same (or worse) from Saturn rockets. |

Because hardware is liberated from pads all the time. Also, that is why there is a FOD program, so as to eliminate or reduce debris.There are many reasons it happens. - Under designed
- Wear due to repeated exposure the launch environment
- Weakening from the weather environment
- Poor installation
And it doesn't matter whether what is on the pad, Saturn V, Shuttle, Delta, the debris can damage any of them.When the solar array broke free from Skylab, some debris hit the S-II interstage which damaged some harnesses and prevented the second plane separation. Foam hit one of the IEA boxes on a shuttle SRB causing a severe dent (using this example to show that other items are sensitive to impact other than tiles and foam). |
