An Anon reader pointed out that in the Summer Vacation story I had Rick flying on a Boeing 707. They did not come out till October of 1958 and that was with PanAm.
That was not a critical point to the story so I did not check. Shame on me. For the record after checking Eastern never owned any 707'2. They were DC 8 or 1011's. Double shame on me because I fly Eastern a lot in the late 60's and until they closed in 1991. Thanks for the heads up.
