Even 1968's "Aerial View No. 1", despite the spatial hint of the title, is far from literal. Certain features of structure and color render a literal interpretation of this image as an aerial landscape difficult or even impossible. The attempt at interpretation is both invited and repulsed. But by about 1970, with the "Night Landings" paintings, there was a definite shift away from the previous decade's stubbornly refractive attitude. The "Night Landings" offer a much more definite sense of scale and viewpoint, especially with the aid of the titles. "Night Landings: Nairobi" is not disorienting in the least: we know where we are; we know we're in a plane, we know the plane is landing, and we even know roughly what time it is: we are looking down, and we see vividly the city named in the title, with the surrounding land and water.
