The first Black Brant XI sounding rocket was launched at 6:14 p.m. EDT and flew to an altitude of 200 miles, followed by the launch of the second Black Brant XI at 6:16 p.m. EDT flying to an altitude of 202 miles. The initial assessment from the field showed that the rockets were launched into a good science event and ground based photos/data of the vapor releases were obtained from at least two locations. Preliminary reports state that the scientist for the mission were very pleased with the results.
