The first rule of Fight Club is you do not talk about Fight Club. The Northrop/McDonnell Douglas YF-23 experimental fighter probably caused a few UFO sightings during its fifty secret test flights. Two YF-23s were built during the early ’90s for evaluation as the USAF’s next stealth fighter, nicknamed ‘Black Widow II’ and ‘Gray Ghost’ owing to their paint schemes.

Despite being faster and more agile than the competitor YF-22, it was the YF-22 that won the contract to be produced due to superior agility, becoming the Lockheed F-22 Raptor. Now de-classified (apart from top speed), the two experimental YF-23s reside in museums, meaning Ralph Savelsberg can talk about them.

His recreation of the ‘Gray Ghost’ includes an opening mini-figure scale cockpit, folding landing gear, and more ingenious building techniques in one build than this TLCB writer has used in his entire building career.

Head to Ralph’s photostream by the link above to see all the images. Just don’t talk to anyone about it.
