Back, oh roughly 20 years ago - some enterprising people built 3 ME 262 replicas at Paine Field (the airport where the Boeing 747/767/777 Factory is located). I discovered them when - while taxying out to takeoff for a flight test - we went by an open hangar with a ME 262 sitting just inside (did a pretty good double take when I saw it). Did a little research after that and apparently they were built to the original blueprints but of course with modern engines and instrumentation.
Never saw one fly though
