"Explosive Disaster at United Launch Alliance Test Facility Captured in New Photo"

United Launch Alliance (ULA) suffered a major setback during testing at NASA's Marshall Space Flight Center in Alabama, resulting in a gigantic fireball erupting at the company's test facilities. The incident involved a ULA Vulcan Centaur V upper stage, which erupted in flames due to a massive cloud of hydrogen combusting, sending debris flying dozens of feet into the air. The explosion could add even more uncertainty to the development of the ULA's Vulcan Centaur heavy-lift launch vehicle, which has already been delayed due to the unavailability of Blue Origin's BE-4 and BE-3U rocket engines.
