XB-47

The museum has the an XB-47 (46-0066, although there seems that an extra "0" was added at some point, as it's more commonly known as 6066), the second X-47-type aircraft constructed and the oldest surviving such aircraft.

While pictures of the XB-47 6065 are fairly common, I've been able to track down only a single vintage 6066 photo, in the San Diego Air and Space Museum's archive.

YouTube has a video regarding Chanute's XB-47, including some video of the mostly-stripped interior of the aircraft.

The B-47 Stratojet Association has an extensive Website, with photos, information on B-47 versions, stories from B-47 crewmen, and much more.
