This is the McGregor, TX location of SpaceX. I live near here and have heard several rocket tests.
Scientific - Misc
SpaceX headquarters is located in Hawthorne, California, near Los Angeles International Airport. Our vehicle manufacturing and design integration facilities are housed in Hawthorne’s 550,000 square foot facility, and it is here that we build all our space systems 'from the ground up'. Engine and large-scale structural testing occurs at our 300-acre test site in McGregor, Texas, near Waco. SpaceX operates launch facilities at the Kwajalein Atoll (Reagan Test Site) in the Marshall Islands, at Cape Canaveral, Florida, and at Vandenberg Air Force Base in California. SpaceX also maintains offices in Washington, D.C.
