[4] Module 1 | The significant milestones and key events in the historical development of the aviation and air transportation industry.

7. **Jet Age (1950s):

The introduction of jet airliners, such as the Boeing 707 and the Douglas DC-8, revolutionized air travel. These faster and more efficient aircraft reduced travel times and increased passenger capacity. For example, the Boeing 707 made transatlantic travel more affordable, ushering in the era of mass tourism.

8. **Airline Deregulation Act (1978):

This U.S. legislation deregulated the airline industry, allowing carriers to set their own routes and fares. It led to increased competition, lower ticket prices, and the expansion of airline services. Southwest Airlines, for example, emerged as a successful low-cost carrier during this period.

9. **Introduction of Wide-body Aircraft (1970s):

Planes like the Boeing 747 and the Airbus A300 allowed airlines to carry more passengers over longer distances. The 747, often called the “Jumbo Jet,” became an iconic symbol of air travel.
