Today we're going to discuss the history of the postal service. In the 19th century, mail was delivered by horse-drawn carriages, which were slow and often delayed by weather. The introduction of the railway in the 1840s revolutionized mail delivery, cutting travel time from days to hours. However, it wasn't until the early 20th century that airmail became common, allowing letters to cross continents in just a few days. Interestingly, the first official airmail flight took place in 1911 in England, but it was only a short demonstration. So, the key turning point for speed was actually the railway, not air travel.
