Commercial Aviation put Las Vegas on the map. George Crockett opened Alamo Airport in 1942 which created a hub for his airline and allowed for further commercial traffic. This site is significant because it was the original location for present day McCarran International Airport. During the 1940s the government needed an airport to further military training and Crockett agree to lease the land. Due to his dedication and sacrifice the county was able to provide necessary pilot training for World War II and contribute to the atomic testing project. Howard Hughes bought the facility and renamed the airport McCarran International after Senator Pat McCarran. Senator McCarran played a huge role in the development of aviation and encouraged ethical business practices and competition among the airlines. Today McCarran International Airport is the fifth busiest in the United States and tenth throughout the world.
