Check out this article at
RetroMechanix.com on the Bell D188, a VTOL fighter proposal for the USN that preceded the D188A/XF-109:
The article is accompanied by an image gallery featuring 160 images reproducing the original proposal brochure and color photos of the desktop model. Many high resolution drawings and illustrations are featured throughout, along with a detailed technical description of every aspect of the aircraft, an unusual beast powered by 11 jet engines(!) More documents on this design will be featured in Part 2 of this article in the near future. Enjoy!
