Re: 1977: Lockheed Have Blue

December 1, 1977 - First flight of Lockheed's top-secret stealth aircraft project designated Have Blue
Have Blue was the code-name for Lockheed's "proof of concept" (i.e. prototype) Stealth Fighter program which preceded the F-117 Nighthawk production stealth aircraft project. The Have Blue was the first fixed-wing aircraft designed from an electrical engineering (rather than an aerodynamic) perspective. The aircraft's plate-like, faceted shape was designed to deflect electromagnetic waves, making the plane essentially invisible to radar
