I saw you work rocket motors so I thought I might pass this piece of info on. I was hired to help perform a weld/ composite repair on a hybrid rocket motor for Lockheed Martin about three weeks ago. My part was the welding part of it. The repair took 21 hours straight on the test stand in gusting winds on a 56 hour straight shift. We performed a 120 sec burn on the motor which is now a new worlds record. The burn was an awsome sight to experience, it was my first, & the whole trip was a blast something I'll never forget. Just thought you might dig the info. I hope & pray you get well, God Bless.
