Global Security Newswire reports that defense officials are close to finishing their investigation into the failure of the HTV-2 hypersonic vehicle on April 22:
A Defense Advanced Research Projects Agency review board “is in the last phases of its internal review” of the Hypersonic Test Vehicle-2’s maiden flight test and should report out in “the next month or so,” Zachary Lemnios said at a breakfast session with reporters this morning. “When that review board finishes their work, we’ll come out with a statement on exactly what’s happened.”
