"In order to capture the concept of flight, Saarinen used curves to create spaces that flowed into one another. The exterior's concrete roof imitates a bird in flight with two massive "wings." The interior consists of a continuous ribbon of elements, all whisking themselves in from the exterior, so that ceilings continously run into walls and those walls become floors."

The buildings has a lateral approach (vehicular flow), and a frontal approach (the pedestrian flow). In this way, the architect hierarchizes the pedestrian flow. The organic geometry of this building creates a remarkable entrance using the large roof. This brutality building make a sequences of symmetric galleries. The exterior recreated a contrast of the color by the material. The subtle and fine white covering makes the form of a bird, and the transparency of the glass it diffuses with the sky.

Saarinen used reinforced concrete to created an unique structure, in this way, the structure is floor and wall, and horizontal circulation, the concrete is the acoustic controller. The building receives natural light by the spaces in facade that are not structure. The interior spaces used the natural color material to recreate the only structural piece. The color of the railings tries to confuses with the concrete.

The circulation represent a pretty important part of the design on this project. A sequence of ramps communicate the two cellular blocks of program, the stairs connect the different levels of the terminal. A big staircase flows down as a river inside the building.
In this picture, The railings makes a spiral rhythm that flows down to the principal space. The color of the ramp also contrast with the white concrete. There is also a rhythm in the staircase using a pattern on the steps.
