U shaped wings

Some time ago there was a magazine cover showing a twin engine
aircraft
with a U shape in each wing. The U's curved downward then up again
with engines and props within the U.
When did that occur and what magazine was that; anyone know? A
vague memory
points to popular mechanics or popular science.
