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. It's amazing that the Canadian aerospace industry was once capable of producing such advanced concepts!
