UPDATE: The 30th Space Wing seems happy, based on their Tweet: 30th Space Wing Yet another launch from good ole Vandenberg! To tonight’s dedicated launch watchers, go warm your fingers and toes!
An Atlas V lifted off at 11:14:30 p.m. PST from Vandenberg Air Force Base carrying a classified National Reconnaissance Office payload (NROL-39). The webcast was ended at just under four minutes into the flight after shroud jettison at the request of the NRO. The flight was nominal for the portion that was webcast. ULA might make an announcement later as to the mission result, or perhaps the NRO will do so.
