Revell even had a model of it. It looked like a frisbee. Fooled everyone.
I joined the Air Force in 1987, and in late 1987 or early 1988, I built a model of the, as of then, not officially announced B-2 Bomber. I remember sitting in an office in the late fall of 1988 waiting on some paperwork somewhere on Goodfellow ABF in San Angelo, TX, when I read a story where it was officially announced.
The Revell model was surprisingly close - the only real difference was how the rear of the wing looked on the model versus the real thing. IIRC, Revell's wing was straight across the back, versus the cut/angled version of the real aircraft.
