United Launch Alliance kicked off its 2018 launch campaign with a Delta 4 rocket flight at 2:11 p.m. PST (5:11 p.m. EST; 2211 GMT) Friday from Vandenberg Air Force Base in California. Gusty winds forced officials to call off a launch attempt Wednesday, and technical problems halted a countdown Thursday multiple times. The Delta 4 launched with a top secret spy satellite for the National Reconnaissance Office.
