Aviation Leak claims that the US may have been operating a secret orbital spaceplane system in the 1990s, now quietly cancelled for unknown reasons.
I don't know what to think of this. The basic design doesn't seem outrageously absurd to me, since ideas along these general lines have been batted around ever since the 1950s.
That business about the revolutionary fuel, "a boron-based gel having the consistency of toothpaste and high-energy characteristics, but occupying less volume than other fuels," smells funny; it strikes me as the kind of thing one usually hears associated with hoaxes. But apparently a fuel based on ethyl borane was proposed for the XB-70 supersonic bomber back in the fifties, which could make this either more plausible or just a cleverer hoax.

Date: 2006-03-07 02:36 pm (UTC)As for the toilet seats, I happen to know that they cost that much because they had to create a new mold for the toilet seats, the old one having been lost or destroyed when the company that sold the Pentagon its last order had gone out of business. The Pentagon's toilets are non-standard enough that they couldn't just buy mass-market commercial toilet seats, so they had to pay for everything, and they had to do it through the procurement process, the regulations in which add expense. So, indeed, the first order of toilet seats cost them way the hell too much per seat. But that's what happens when you place a special order and you'll always be the only customer.

E.g. their recent habit of using somewhat radiation-hardened variants of commercial PC electronics, so that it isn't necessary to fund a lot of design work. And the fact that all their planetary missions seem to have standardized on exactly the same 1-megapixel square monochrome CCDs. Of course this stuff wasn't flashy enough to stay in the budget this time around...
