re: #1131 Kosh’s Shadow

Some stuff was declassified, or at least leaked.
A couple of years ago, AvLeak published an article on a military two stage to orbit system. The first stage was very similar to an XB-70, and it air launched a second stage. These fit a lot of the “triangular object” UFO stories.

And I find it interesting that an article when the SR-71 was retired said that the military wouldn’t be retiring it if they didn’t have a replacement. That was about the time this system went into service.
And the same comment is probably applicable now that it has been retired as well.

Advanced aircraft and spacecraft at “Area 51” - yes.
Aliens, no.

“Triangular objects” would be lifting bodies, that NASA’s been looking at as far back as the late ’60s and early ’70s. In the opening credits for The Six Million Dollar Man, the producers used NASA file footage of a lifting body crashing on landing (it was actually unmanned) as the “crash” that Steve Austin was in, leading to his becoming a cyborg.
