CLANGBIRD. LOL.
What’s the origin of this character?
I do believe that's a creation of USAF types.
First time I heard it was while I was workin' on the B-1A. (Although the joke was supposedly aimed at the "High Command" out in the Pentagon along with Congress.)
(We were so busy chasing Specification Changes I'm surprised we managed to actually build those four prototypes. Not to mention that they all looked alike.)
