Aircraft have architectures that can be characterized by how they resolve some major design questions, such as engine location, wing location, landing gear layout, and more. For many decades, most jet aircraft designed for passenger transport have the following characteristics:

• Engines housed in nacelles slung underneath the wing (as opposed to engines built into the wings, or engines mounted on the rear of the fuselage)

• Wings that join the fuselage at the bottom (as opposed to the top or middle)

First, do an online search to find an example and a counter-example of this type of design from each of the following manufacturers: Boeing, Embraer, Tupolev, Bombardier. Next, do some online research and answer the following question: What qualities important to aircraft does this design provide?
