“Legendary Lockheed aircraft engineer Clarence ‘Kelly’ Johnson,
designer of the F-104, U-2, and SR-71, and his wife observed a
huge Flying Wing over the Pacific from the ground in Agoura.
Meanwhile, one of Johnson’s flight test crews aboard an WV-2
(see EC-121) spotted the craft from Long Beach, California.
USAF (Project Blue Book) concluded these trained observers had
seen a lenticular cloud, even though Johnson considered and
ruled out that explanation.”
