Check out this article at RetroMechanix.com on a bizarre Avro VTOL supersonic jet fighter proposal to fulfill US Navy specification TS-140 in 1956:
It featured two pairs of unswept wings with four jet engines mounted on each wing tip. The aircraft’s “X-wing” configuration is apparent when viewed from head-on, prefiguring the famous Star Wars design by several decades. Never before published online, it includes a 73 image slideshow reproducing the entire proposal brochure with many high resolution drawings, artist’s impressions, and photos. Would make an exciting scratchbuild!
