The modern jet didn’t really become ubiquitous until the 1960s. Pan Am started flying the B707 in Oct. 1958. There were very few passenger jets until the 1960’s. Don’t forget, Air Force One was a variation of the 707 until the 1990s.
You aren't telling me anything I didn't already know.
Why are you telling me this? Does it perhaps refute anything I stated in my previous posts?
If you intended only to amplify my statements, then say so!
