Is there a good source of information on specific drop tests — dates, results, even photos? I'm specifically looking for any information I can on drop 86-4. It is referenced in a June 1970 paper on predicting the loads and stresses on the Apollo parachutes, but I can't find any other mention of 86-4. |

If your inquiry pertains to the chute purchased via Lunar Legacies in January of last year, it was utilized for a separate series of non-qualification drop tests to obtain failure analysis data. |

Thanks for the quick reply! It does pertain to that, so any information you could provide about those tests would be greatly appreciated. I don't even know what a "non-qualification drop test" is.Is that "86-4" still the one mentioned in the paper I linked to? (You can do Cntrl-F for 86-4 to find it a few times in that 350-page paper.)

Following conclusion of the qualification series, NASA found it had remaining, un-utilized parachutes and took the opportunity to conduct additional drops not programmed into the original test regime. These supplemental drop tests generated data to inform potential future NASA efforts. |
