I was expecting something closer to this...
Show-off.
Back in the '80s, I worked on the Cryogenic Fuel inerting, Life Support, and Survival Systems on these, and the other "gliders" in the US Intelligence Gathering mission, for a company that contracted out from the former Skunk Works. Looking back on that, I guess it was kind of like Chrysler farming out their Hot Rods to venders, to make those rare cars we all look for today...
