It reports that big aerospace firms quietly ran internal UAP research and small collaborations—like Douglas and McDonnell-Douglas exploring gravity and exotic materials, studying Blue Book cases, and pursuing various leads with people such as Joseph M. Brown, Chan Thomas, Paul Wilson, Stanton Friedman, John Scheussler, Ronald Evans, Vallee, Ben Rich, and Boyd Bushman—yet these efforts produced little publicly verifiable evidence or broad, transparent results.
