Among the many things taken for granted today is long-distance travel by jet airliners. So common is long-distance air travel that there have even been around-the-world races for general aviation aircraft. One forgets that regularly scheduled intercontinental commercial air travel only came into being after World War II.
The roots of long-distance flight lie in the five years after the First World War. In the early post-war period, aviation spread its wings in ever greater long-distance flights, culminating in the first round-the-world flight in 1924.
