Suborbital Passenger Travel
Found out a bunch of interesting things when researching this article, including the existence of the antipodal bomber, something I had no idea that both Nazi Germany and the Cold War Era US had actively researched. i always look at those innovations that were actively pursued back then, and how different our world would be if even a fraction of them had been followed trhough on.
