A photographer in California got this photograph of the jet a couple of weeks ago as it was flying near Edwards Air Force Base. Aviation Week, which reported on the existence of the jet, published this same shot and presumably used it to estimate the jet’s altitude in the photograph as 20,000 feet. This is all presuming that the plane in the shot is the new jet in question, which it might or might not be. Remember that the Air Force has only confirmed the existence of the program and no details, so it could well be another secret program. [links]
