Alright. The SR-71 was never really an Air Force thing, but a CIA thing. By the way the designation for it started out as "RS" instead of "SR" (nice Camaro connection huh?). Once the SR-71s got axed by Dick Cheney back in the early nineties, NASA still kept one for "testing purposes"...uh huh, right.
The U-2s started the same way more or less (CIA project, before the SR-71) but the AF got a hold of them and still uses the things (props to Kelley Johnson). And I hate to disagree (slightly) with the Father, but the Camaros were chase cars for landings...copilot may be a stretch
And if stuff is gonna get trashed from a UAV, the MQ-9 Reapers will probably handle that these days.
