text_A: While the "Baja Scorpions" were working on the F-117, there was also another group at work in secrecy, known as "the Whalers" working on Tacit Blue. A fly-by-wire technology demonstration aircraft with curved surfaces and composite material, to evade radar, was a prototype, and it's stayed that way. Nevertheless, this strange-looking aircraft was responsible for many of the stealth technology advances that were used on several other aircraft designs, and had a direct influence on the B-2; with the first flight of Tacit Blue being performed on 5February 1982, by Northrop Grumman test pilot, Richard G. Thomas.
