Reminds me of this passage from Bill Bryson's great memoir "The Life and Times of the Thunderbolt Kid":
Every week brought exciting news of things becoming better, swifter, more convenient. Nothing was too preposterous to try. MAIL IS DELIVERED BY GUIDED MISSILE The Des Moines Register reported with a clear touch of excitement and pride on the morning of June 8, 1959, after the U.S. Postal Service launched a Regulus I rocket carrying three thousand first-class letters from a submarine in the Atlantic Ocean onto an airbase in Mayport, Florida, one hundred miles away. Soon, the article assured us, rockets loaded with mail would be streaking across the nation’s skies. Special delivery letters, one supposed, would be thudding nosecone-first into our backyards practically hourly.By the way, isn't it strange that, describing something that's supposed to be exciting and beneficial, a key word is "unmanned"?
“I believe we will see missile mail developed to a significant degree,” promised Postmaster General Arthur Summerfield at the happy celebrations that followed. In fact nothing more was ever heard of missile mail. Perhaps it occurred to someone that incoming rockets might have an unfortunate tendency to miss their targets and crash through the roofs of factories or hospitals, or that they might blow up in flight, or take out passing aircraft, or that every launch would cost tens of thousands of dollars to deliver a payload worth a maximum of $120 at prevailing postal rates.
The fact was that rocket mail was not for one moment a realistic proposition, and that every penny of the million or so dollars spent on the experiment was wasted. No matter. The important thing was knowing that we could send mail by rocket if we wanted to. This was an age for dreaming, after all.
