Marc, a new design for the CSS landing zone was created and built in the computer with dimensions needed for our location and needs. Posts and beams and a roof is nothing unique or proprietary. Many buildings have posts, beams, walls and a roof. Some even have curved elements. Architects study history and theory and bring those concepts and examples to the table. The AJX site has unique conditions and calls for appropriate design responses to meet those needs and functions. Form follows Function. CSS is in need of a multipurpose facility to move forward into the next 50 years of free flight. Best.
