The US Postal Service has been a key player in technological advancements for over 250 years, especially in mail delivery. A major breakthrough occurred in 1918 with the introduction of airmail, born from collaboration with the Army Signal Corps. Early airmail pilots faced great risks, with 34 fatalities between 1918 and 1927. The Postal Service not only established reliable airmail delivery but also developed crucial aviation infrastructure, paving the way for modern commercial aviation and mail transportation systems.
The Postal Service had to develop all of those things just for getting the mail delivered.
You take your letter, you put it in a mailbox, and then it shows up somewhere in a couple of days. The truth is that that piece of mail gets touched by a lot of people and machines.
