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.
Revell had been very good generally at ferreting out aircraft designs. But they missed the boat completely on the stealth fighter. Some hitech writers like Clancy got taken too.
