Some NASA colleagues and I visited SpaceX in Hawthorne, California, on Thursday. Thanks to SpaceX engineers Sam DiMaggio and Jessica Jensen for the guided tour. We saw a Dragon spacecraft being built, as well as several rocket engines.
Sam DiMaggio, who leads the loads and environments groups, said they have a policy that no margin is added to any loads at any step in the process. Then at the end, all disciplines get together and decide what the overall factor should be.

I wish that I were 25 years younger and working at SpaceX.
But I take satisfaction knowing that Sam, Jessica, and their SpaceX colleagues are using my Vibrationdata software. 🙂
