I think it MAY be done IF you do not fly as a "normal" arch. Fly parallel to the wind instead of perpendicular to the wind. Hold both ends down and it might work. If enough space is left between the kites. And if they are hooked to the bridle line properly.
I had some information from a book that I bought some time ago. So I scanned a few pages.
OK, did it. I scanned 6 pages and have saved them on Photobucket.
The book also has several pictures, and plans for kites to be flown in train. I do not want to scan them, though as I don't want to break the spine down any more than I have.
Maybe I can figure a way to photograph instead of scan. IF anyone is interested.
