The phrase “unk-unk”, although frequently attributed to Rumsfeld, has been frequently used in aerospace, at least back to the 1960s. I suppose he made it popular elsewhere, though.
I gave a presentation to the executive leadership team where I work. Part of the presentation dealt with unknown unknowns.
My Power Point side had the Rumsfeld quote and a phot of me and Sec. Rumsfeld.
My boss was in the room and I heard “You really went there” under his breath.
Heck yea. I have a phot of me with a member of my short list of personal hero’s, of course I’m going there.
Unnngh?
