Seat 2A,
You never cease to amaze me, this time posting that ultra cool TWA ad from 1967. I assume, besides flying Boeing 707 "Star Stream Jets", TWA was also operating a fleet of 727s, Convair 880s and DC-9s, yes? I can only imagine what US domestic travel would have been like if TWA really did take delivery and operate SSTs like the ad envisioned. Well, that was the world of Trans World Airlines, back in the day!
