A powerful explosion destroyed part of Northrop Grumman's solid rocket motor production facility in Promontory, UT. Unbelievably, no serious injuries resulted from the blast which sent shockwaves through the surrounding area. The facility, known as "Rocket Ranch," is a cornerstone of the US solid rocket motor (SRM) production capability and plays a central role in some of the nation's most critical defense and space programs. An investigation and safety review are underway. youtu.be
