In the 1970s, the supply of gas was affected by price controls imposed by the Nixon administration and then by an oil embargo by Arab members of the Organization of Petroleum Exporting Countries (OPEC).
As a political move aimed at pleasing voters, President Richard Nixon announced in 1971 (prior to his reelection campaign of 1972), "I am today ordering a freeze on all prices and wages throughout the United States.” The wage and price controls the Nixon administration sought to put in place interfered with natural market forces and oil supplies were reduced. That problem was magnified in 1973 when oil exporting countries in the Arab world imposed an embargo on supplies to the United States due to US support of Israel in a war that Israel was fighting against a coalition of Arab states.
Both factors -- lingering efforts at price controls and continued control of the oil and gas market by OPEC nations -- played into the long lines at gas pumps seen in America in the 1970s.

Explanation:
Commercial and Freight aviation has come a long way. From using out dated B-16 bombers for passengers we are now using beautiful technology like Boeing-747-400, Airbus A-380, and the massive and intimidating freighter AN-225. Imagine the fact that we come from a small 2 passenger glide with one propeller to Fighter Jets that can go more then 400 KM/H all over the world like the American F-18 or the American Stealth B-2 bomber. Commercial aviation also came a long way. Before we used B-16 airplanes that couldn't fly high up which caused turbulence and discomfort. The break thru in aviation was the first ever commercial airliner to break the Altitude of 43,000 feet was the Boeing 747-100.
