Space.com has vid of prototype test.
What is the link to the vid, or an I supposed to wander around space.com?
https://www.space.com/astroclipper-space-plane-concept-cargo-passenger-flights.html. . .not this as it is computer grahics.
Can’t find it.
Nothing new on that webpage.
Nothing unusual or “leading” edge.
No articles mentioning CG problems you state as fact, nothing.
And any classified stuff would not be released to a private company, and leading edge stuff would be at Groom Lake still under a shroud.
Cheers
