This is the trajectory that I think USSF-52 (OTV 7) might be flying, based on Navigational Warnings. A short low altitude 51.5 degree inclined coasting orbit followed by a dogleg to a higher orbit, perhaps a 74-degree inclined HEO as that fits the 2nd stage deorbit area and time. pic.twitter.com/MFUyeVAzLE
