It's an axiom of the "Black" experimental aircraft
programs that if you see it, it's already obsolete.

I was hoping that someone would comment on the rumors
that there is actually a two-tier technology here. The
PTB have a few early models to keep the people busy guessing
(like various NASA projects)
while the real stuff is in use-out there.

The biggie: we have working starships (or one, at least)
and have actually been to another solar system. But, it's
likely just another wish waiting to be achieved.
