Lockheed Martin constructed the first P-791 Lighter than Aircraft (LTA -a prototype of the larger LMH-1 featured in my novel) at the Skunk Works in January 2006.
“The Skunk Works® team completed the construction of its latest digital factory in Palmdale, California. This flexible facility enables a collaborative digital approach to increase the speed, agility and effectiveness of aircraft manufacturing through advanced robotics, artificial intelligence and augmented reality.” (Lockheed Martin, Online, 2021).
