Which transportation vehicles has changed people`s lives?
As opposite to cars and bicycles, airplanes changed human lives in a
most radical way. While automobiles in most cases link people
living within the same country, a transcontinental aircraft is capable
of reaching most remote locations on earth within days and even
hours thereby connecting people and carrying goods and ideas. Fast
and inexpensive air delivery system benefits all aspects of social
well-being, from industrial needs to emergency and rescue
operations.
Moreover, modern tourism based primarily on air travel makes it
possible to visit virtually any country or even countries within
regular vacation time and, therefore, serves the most noble purpose
of establishing mutual understanding and trust between nations.
On the other hand, military airfare also drastically changed both
military doctrines of the nations with modern air forces and
battlefield tactics by significantly reducing number of military and
civilian casualties in armed conflicts, increasing intensity and
effectiveness of assault on enemy troops thereby reducing total
duration of a conflict.
To summarize, aircraft revolutionized modern life in many areas in
most cases serving to the benefit of humanity.
