Bill McDonald
Illustrator who in 1992 drew the 'Tehachapi Triangle' or XF-131 Super Sentinel from descriptions by four Northrop and Lockheed engineers working the Tejon and Helendale radar ranges. Fox used his render in The X-Files. UAP Gerb treats this as a line independent of Edgar Fouché's TR-3B.
