As a bod with connections to the AD community, the Aurora is not a new phenomena.
It was reported in open press a good few years ago, albeit open press meaning scientific journals.
It was reported that the Uncle Sam had come up with the jet of all time, something that could go round the globe in a few hours, putting Quantas to shame for getting to Aus from CONUS.
Only snag being that its stealth concept was useless due to various issues which I'm not going to describe here showing up really easily.
