The details I forgot to include are that the show briefly covers "The Outlaw" with Jane Russell, a short clip of her cleavage. The breast content occurs just before the half-hour mark.
The clip with Busty Gal is a must-see, while the narration comments on Hughes' unreasonable fear of speed bumps damaging female breast tissue, the camera focuses on this Beautiful Gal's chest AS IT BOUNCES UP AND DOWN IN SLOW MOTION! She reminds me of Merilyn in this attached photo.
The production credits are supposed to be on the NGEO website, but have not been posted yet, I don't know the model's name, but maybe she'll model her slim and stacked body again in future.
Howard Hughes was one of us!
