After World War II air transport became very popular for the military and commercially. By 1939 there were more than 300 air transport aircrafts in the U.S and manufactures were producing 50,000 planes per year. With the introduction of the DC-4 aircraft a lot of things changed. The DC-4 made its first flight in February 1942 when it was known as the C-54 in the military. In 1947 the DC-4 had its first major modification. The modification made the aircraft the most economical piston engine transport in the airline service. In 1953 another version was created the DC-7. This version was larger than the DC-6 and was the first airliner able to fly nonstop against prevailing winds. The DC series aircraft were also facing competition from the Constellation series that were purchased by Pan Am. With the improvement to the airplanes commercial travel became more popular but along with popularity came congestion in airports and the complex routes. The addition of food on long flights helped balance out these issues for travelers. The air method played a great role in the Cold War between East and West. During the previous wars the United States used bombers as their form of aerial attack but during the Cold War they switched to jet aircrafts. After the attacks on Pear Harbor officials agreed with creating a independent air force.
