Thanks for all the replies. I found a pic from 2003 on this site and printed it out. When I stand the printed picture of the terminal on its side, it starts to take on an elliptical shape..more oval-shaped, like the earth's orbit around the sun..lol It must be an optical illusion, what with the 32 support beams and cables on top. I even took a ruler (probably not an accurate measurerment on a 2-d picture) and I see one side measures over 3 inches across and another side is a little less than 1 1/2 inches in length. Yet, when viewed looking directly at it, it appears as a circle. I also see that the roof curves upward and is not completely flat. I can see why a previous post stated it was complicated to build.
By the way, I only plan on building the actual terminal, nothing inside. It will be 1:500 scale and I plan on building EVERY terminal and roadway/parking lots, etc at JFK
on separate boards, stacked up in layers, so to speak. This will take years, if not at least a decade...lol. I wonder how JFK
will be 10-20 years from now. Pics of construction updates will be posted on model airport-related websites.
I posted the original question to this forum because I know you guys are full of commercial aviation knowledge.
