What Made The F-117 So Special
The flat exterior of the aircraft had the critical role of deflecting radar waves. Another radar deflecting device was the pair of General Electric turbofan engines. These powered the jet without producing afterburners. Everything done was to keep the plane hidden.
What Else
The interior of the jet also played a significant role. Pilots had the ability to fly with infrared sensors, satellite-sent radio signals, inertial guidance, and digital maps. The conventional internal radar systems were replaced by these navigational tools, which would make this plane even more special.
